Jefferson County Idaho Fairgrounds Events

Jefferson County Fairgrounds is located at 319 Veteran Memorial Drive, Rigby, Idaho 83442. The grounds host the annual Rigby fair, livestock competitions, rodeo events, and other community activities connected with agriculture and rural life in eastern Idaho.

Rigby is the county seat of Jefferson County, north of Idaho Falls. Visitors generally reach the area through US-20 and local roads serving Rigby. During major events, temporary signs and traffic arrangements may direct visitors toward designated entrances and parking areas.

Jefferson County’s fair program has an important youth-agriculture component. The county works with University of Idaho Extension and its 4-H program to coordinate youth projects, livestock shows, judging, and exhibitor information. The City of Rigby manages the rodeo grounds and maintains the rodeo event schedule, while county fair information and exhibitor rules are handled through the county’s fair administration.

One detail matters when planning a visit: Jefferson County has two separate annual fairs—the Rigby Fair and the Mud Lake Fair. The Rigby fair takes place at the main fairgrounds in Rigby, while Mud Lake has its own fair and schedule. Check the location on the event listing before traveling.

The Rigby site includes an arena and multiple event spaces used for livestock and public activities. Published venue information lists a main building and rodeo arena, but exact acreage, building counts, and current seating arrangements should be confirmed with the venue rather than estimated.

Upcoming Events at Jefferson County Fairgrounds

The main Rigby fair is the largest annual event at Jefferson County Fairgrounds. Its schedule combines livestock competitions, youth project exhibits, food and commercial vendors, and rodeo entertainment. Other activities may be scheduled during the year, but visitors should check the current calendar instead of assuming that every event type returns annually.

Events and activities

Fair programs and the grounds’ usual functions include:

• Jefferson County Fair: Youth exhibits, livestock shows, family activities, commercial vendors, and scheduled entertainment.
• Rodeo performances: Events managed through the City of Rigby rodeo grounds schedule.
• 4-H and FFA livestock competitions: Animal judging, showmanship, and market-animal activities.
• Horse shows and dog events: These may appear in the fair program, depending on the year.
• Open-class exhibits: Community entries in arts, crafts, food, gardening, and other categories listed in the fair book.
• Tractor and farm-related activities: The fair program may include tractor displays or related competitions.
• Community gatherings and rentals: Facilities may be available for approved events outside fair week.

Do not assume that gun shows, motocross, flea markets, demolition derbies, or concerts are part of every year’s program. Confirm a specific listing before making plans.

Seasonal patterns and facility rentals

The Rigby Fair is held in August. Youth entry deadlines, livestock preparation, and fair-book publication occur before the event, so exhibitors should begin planning well ahead of fair week.

The fairgrounds may also be used for events outside the annual fair. Anyone considering a private gathering or public event should ask about available buildings, arena use, rental charges, insurance, setup times, and cleanup requirements.

For current dates and exhibitor rules, Jefferson County’s fair information and the University of Idaho Extension office are the appropriate starting points.

The Jefferson County Fair Itself

The annual event held at the Rigby grounds is generally referred to as the Jefferson County Fair or Rigby Fair. The county also runs the separate Mud Lake Fair, so the location should always be checked when reading schedules or fair-book announcements.

Typical fair timing: August

The county’s 2026 schedule listed the Mud Lake Fair for August 5–8, 2026, and the Rigby Fair for August 10–15, 2026. These dates have passed. The 2027 schedule should be confirmed through the county’s current fair calendar rather than inferred from the 2026 dates.

Livestock shows and exhibits

The fair’s 2026 livestock rule book and schedule provided information for youth animal entries and competitions. Fair activities can include swine, sheep, goats, cattle, poultry, rabbits, and other small-animal projects, depending on the published classes for that year.

Youth exhibitors should check animal eligibility, weigh-in requirements, identification rules, health paperwork, and show times in the current livestock rule book. Open-class exhibitors should use the fair book to confirm whether entries such as baking, crafts, photography, gardening, sewing, and other creative projects are offered.

Rodeo, midway, food, and entertainment

Rodeo events are a significant part of the Rigby area’s western-sports calendar, but the exact performances and dates are managed separately from the general fair program. Check the rodeo schedule for event times, ticketing, and any special admission arrangements.

The fair can include food concessions, vendor booths, and family activities. The current program should be consulted for carnival availability, ride prices, wristband offers, entertainment, and the hours that vendors are open. No specific ride count or annual discount should be assumed without confirmation.

Admission and parking

Admission prices and parking policies can vary by event. Some activities may be ticketed separately, particularly arena performances. The fair office or event organizer can confirm current gate charges, rodeo tickets, parking arrangements, and any child or senior policies.

Parking demand can increase during popular livestock shows and rodeo performances. Follow the signs at the fairgrounds and arrive early if you need time to reach a particular building or arena entrance.

Facilities and Grounds

The Rigby fairgrounds contain multiple spaces for animal exhibitions, public events, and community use. Facility availability varies according to the event schedule and any ongoing preparations for fair week.

Arena and event buildings

The rodeo arena is used for scheduled western-sports events. Published venue information has listed capacity of approximately 2,500 for the rodeo arena and around 500 for the main building; these figures should be confirmed with the facility before organizing an event, as layouts and permitted capacities can vary.

Livestock areas support animal check-in, showmanship, and judging. The fair’s current rule book identifies the spaces and procedures relevant to participating exhibitors. Ask the fair office about stall availability, animal arrival times, equipment storage, and any restrictions on overnight animal care.

Camping, parking, and visitor amenities

Some venue listings describe RV hookups at the fairgrounds, but visitors should confirm whether spaces are available for their particular event and whether reservations are required. Do not assume that every fair attendee can camp overnight on the grounds.

Information about ADA parking, accessible routes, restrooms, first aid, ATMs, and concession availability should be confirmed with the organizer if you have specific needs. Services that operate during fair week may not be open for smaller events.

Vendor and Exhibitor Information

Jefferson County Fairgrounds offers opportunities for exhibitors and vendors through its annual fair and approved facility rentals. The requirements differ for commercial booths, open-class exhibits, and 4-H or FFA animal projects.

Applying for a vendor booth

Commercial vendors should request the current application and rate information from the fair office. Before submitting an application, confirm:

• Booth size and indoor or outdoor placement.
• Rental fees, deposits, and payment deadlines.
• Electrical service and other utility availability.
• Setup and removal times.
• Insurance, permits, and food-service requirements.
• Rules for signage, sales, and overnight storage.

A booth is not secured until the organizer confirms acceptance and payment arrangements. Vendors planning for 2027 should use the current application rather than rely on rates from an earlier fair.

Entering exhibits and livestock

The county publishes fair books and livestock rules for participants. These explain registration procedures, entry deadlines, judging classes, animal requirements, and show times.

For youth projects, contact University of Idaho Extension in Jefferson County. The Extension office can help families understand 4-H enrollment and project requirements, while the fair board handles event logistics and fair-specific rules.

Getting to Jefferson County Fairgrounds

The main Rigby fairgrounds are at 319 Veteran Memorial Drive, Rigby, Idaho 83442.

Driving directions

• From downtown Rigby: Follow local roads toward Veteran Memorial Drive and use the designated fairgrounds entrance.
• From Idaho Falls: Travel north toward Rigby using the regional highway network, then follow local directions to the fairgrounds.
• From US-20: Take the appropriate Rigby-area exit and follow local roads and event signage to the venue.
• From Mud Lake: Check the destination carefully before leaving. The Mud Lake Fair is a separate event at a different location from the Rigby Fair.

Traffic patterns may change during the August fair and rodeo. Do not assume a shuttle service or regular public transportation will be available. Rideshare users should coordinate a pickup point that does not obstruct event traffic.

4-H and FFA at Jefferson County Fairgrounds

University of Idaho Extension supports youth development and agricultural education through Jefferson County’s 4-H program. The Extension office is located at 210 Courthouse Way, Suite 180, Rigby, Idaho 83442.

Extension and 4-H phone: 208-745-6685

Youth livestock and project competitions

The fair gives young participants a place to demonstrate the work they have done in livestock, animal care, and other projects. Depending on the year’s rules, competitions can include animal fitting and showing, judging, and market-animal classes.

Youth should check with Extension and their club leaders about enrollment, animal identification, required forms, weigh-in times, and project deadlines. FFA participation and the exact list of participating chapters should be confirmed in the current fair program.

Junior livestock sale

The fair’s livestock program may include a market-animal sale for eligible youth exhibitors. Buyers should obtain the current sale rules to learn when the sale takes place, how to register, which animals qualify, and how payment and animal disposition are handled.

The sale provides an opportunity for local businesses and community members to support youth projects. Specific sale dates and procedures should not be assumed to remain the same from year to year.

Special Events Beyond the Annual Fair

The Rigby grounds are associated with more than the annual fair, particularly through the rodeo arena and livestock facilities.

Activities may include rodeo performances, youth livestock shows, horse-related events, and approved community gatherings. Depending on the schedule, buildings and outdoor spaces may also be used for meetings, fundraisers, or other public and private events.

The City of Rigby maintains the rodeo grounds’ event schedule, while county fair information covers the annual fair and exhibitor requirements. This distinction is useful when looking for a specific rodeo or arena performance.

Gun shows, swap meets, motocross, tractor pulls, and demolition derbies should be treated as unconfirmed unless they appear in the current calendar. The fairgrounds’ availability for rental does not establish that a particular activity is scheduled.

History and Community Role

The Jefferson County Fair reflects the agricultural traditions of eastern Idaho, where livestock, farming, and rural youth programs remain important parts of community life. The annual fair gives young exhibitors a chance to present their projects, compete in judged classes, and learn practical skills.

The Rigby Fair and Mud Lake Fair are both part of Jefferson County’s annual fair calendar, but they serve different communities and take place at separate locations. Keeping their schedules distinct helps exhibitors, vendors, and visitors avoid confusion when planning travel or submitting entries.

A precise founding year for the current Rigby fairgrounds, verified historical attendance records, and a complete record of cancellations are not confirmed here. Those details should be checked against county archives or historical fair books rather than stated as fact without documentation.
