OVERVIEW
Each year on the first Saturday in August, we paint the town yellow.
The National Mustard Day Festival in Middleton is a celebration of "America's favorite condiment" and a day of quirky fun for mustard lovers everywhere. Celebrated the first Saturday of August, thousands join the National Mustard Museum in Downtown Middleton for family-friendly games, food vendors, live music, and of course, MUSTARD!
Middleton takes National Mustard Day quite seriously. As home to the National Mustard Museum and National Mustard Day, it is no wonder why this day is marked on everyone's calendar.
The next National Mustard Day will be held on Saturday, Aug. 1, 2026, and festivities include closing Hubbard Avenue downtown in front of the museum and gift shop and filling the street with mustard, brat and pretzel vendors; mustard-themed family-friendly games; kids' activities like a bouncy house and balloon animals; and a stage with live music all afternoon.
The National Mustard Museum is free and open to all, and the gift shop is ready to assist with your mustard needs.
