For Labor Day weekend — Saturday, September 5 through Monday, September 7, 2026 — I can’t responsibly confirm a current, published lineup of New Orleans festivals or timed 5K races from the available listings. I don’t want to send you to a canceled race or an outdated event page.

The major annual draw typically associated with this weekend is Southern Decadence in and around the French Quarter, with parties, parades, and nightlife rather than a traditional fenced-in festival. Check its official schedule before heading out, since individual events and routes can shift.

For a same-day running option, check New Orleans Running Systems’ race calendar and Race Roster’s New Orleans listings before registering; Labor Day weekend can be light on formal 5Ks because of heat and holiday travel.

👉 Are you looking for a family-friendly daytime festival, or are French Quarter/nightlife events what you had in mind?
