National Mustard Day
NEXT: SATURDAY, AUGUST 2, 2025
Each year on the first Saturday in August, we paint the town yellow. Since the very first mustard day celebration in Mount Horeb, Wisconsin, back in 1991, the Mustard Museum has hosted this golden annual event. And, we truly have come a long, long way. That first event occupied about three parking stalls in front of the original museum.
Now, we close streets in Downtown Middleton where thousands gather every year for this engaging street festival!
A family-oriented, fun-filled, sun-splashed outdoor food festival, National Mustard Day features hot dogs, brats, mustard sampling, live music, and games & prizes all for a one-of-a-kind mustard experience. Mustard Day has become one of Dane County’s most anticipated summer outdoor events.
