If you have lived in Piedmont for more than a year, you already know the second Saturday of September belongs to Monroe Avenue. The parade route fills up before the coffee cools. The Old Store's parking lot turns into a maze of repainted dressers and $4 milk-glass. Someone's kid is on a pony. Someone else is judging pies. This year that Saturday is September 12, 2026, and the day has a rhythm most first-timers miss because they treat Founders Day like a single event instead of the hinge the whole downtown swings on.
That's the thesis of this guide. Founders Day is not one festival. It is three things happening in the same six blocks, stitched to the Saturday farmers market you probably already shop, and the locals who plan for that overlap eat better, park closer, and leave with the vendor finds everyone else posts about on Sunday.
What is actually happening on September 12
Piedmont has been throwing this party since the town's founding in 1903. The 2026 edition runs 9 a.m. to 4 p.m., anchored at the Piedmont Baptist Church parking lot at 15 Jackson Ave NW, with the parade rolling through downtown along Piedmont and Jackson.
Piedmont Founders Day features more than 150 local and area vendors, a parade, a 5K, a talent show, pony rides, an art show, a pie and quilt raffle, and a full children's area with wall climbing, inflatables, and face painting.
Layered on top of that, Junklahoma runs the same day, presented by The Old Store. It is the vintage, antique, and repurposed-furniture half of the weekend, and it is scheduled every year as the first Saturday after Labor Day so it lands on the Founders Day footprint on purpose. If you have ever wondered why the crowd on Monroe looks twice as big as the official festival footprint suggests, that is why. You are actually walking through two overlapping events.
The three-part rhythm most people miss
Here is the sequence that separates a full day from a frustrating one.
| Time | Where to be | Why |
|---|---|---|
| 9:00 a.m. | Piedmont Farmers Market, 12 Monroe Ave | The market runs every Saturday 9–1 from May through October 31. On Founders Day it opens with the festival, and produce moves fast. |
| Mid-morning | Parade route, Piedmont & Jackson | The 5K clears the streets first, then the parade rolls. Stake a curb before 10. |
| Late morning to 2 p.m. | Junklahoma at The Old Store + Founders Day vendor booths | The 150-plus vendors thin out by early afternoon. Cash still wins at some booths. |
| 2 to 4 p.m. | Kids' area and talent show | Lines at inflatables collapse after lunch. This is the window if you have small kids. |
The market piece is the part visitors never plan for. Locals do, because a Saturday morning at 12 Monroe Ave is already routine from May 2 through October 31. Founders Day just adds 150 vendors to a block they were shopping anyway.
Where to eat when the funnel cake is not enough
Founders Day feeds you well. Cinnamon rolls, homemade desserts, barbecue, hot dogs, Indian tacos, and food trucks are all on the grounds. What the schedule does not tell you is that by 1 p.m. the lines at the food booths get long enough that walking two blocks off Monroe is faster than waiting.
A short list of what is close enough to matter on a festival day:
- Piedmont Cuisine, 91 Monroe Ave NW. Chinese menu with a full American breakfast and lunch side, including chicken fried steak and egg foo young on the same page. Closed Mondays, open Saturdays 10 a.m. to 9 p.m.
- Sharp's BBQ, half a block off Monroe. A town favorite that regulars name-drop first.
- La Herencia Mexican Grill, Flour & Fennel, and Phoenix Asian Cuisine if you want to sit down away from the festival noise.
- HTeaO, 12031 Northwest Expressway. The tea shop opened on June 13, 2026, sitting between Piedmont, Yukon, and northwest Oklahoma City, with 20-plus flavors and a 2–4 p.m. buy-one-get-one happy hour that lines up almost exactly with the festival's kid-friendly window.
The HTeaO opening is the newest piece of the puzzle. For years, a Founders Day afternoon meant driving into Yukon or back toward Kilpatrick for a cold drink that was not fountain soda. Now you can hit the happy hour, cross Northwest Expressway, and be back at the parade route in under ten minutes.
The parking play
Two facts most Founders Day guides skip.
First, the parade closes the core of downtown to through traffic during its run. If you drive in after the 5K starts, you will circle. Locals park at the school lots on Washington and walk in.
Second, the church lot at 15 Jackson Ave NW is the festival footprint, not parking. Do not plan on it. The lot fills with vendor tents and inflatables before the first booth opens.
If you are hosting out-of-town family, tell them to arrive by 9:15 or after 11. The window between is when the parade snarls everything.
Why Founders Day matters more than a normal small-town festival
Piedmont has grown quickly enough over the last decade that a real chunk of the population has never lived through the town's slower version. Founders Day is one of the few days a year when the newer subdivisions off Piedmont Road and the families who have been here for three generations end up on the same square of grass, buying the same kettle corn, watching the same parade. The festival is the connective tissue for that.
There is a reason the vendor waitlist for Founders Day fills every April, with returning vendors getting first crack and new applicants opening up in May. If you have ever thought about setting up a booth, that April 2027 window is the one to watch on the official Founders Day site.
What comes next on the Piedmont calendar
Founders Day is the anchor, not the finale. A few dates worth putting on the fridge before you forget:
Piedmont Farmers Market keeps running every Saturday, 9 a.m. to 1 p.m., at 12 Monroe Ave through October 31. The last few Saturdays of the season are when the fall squash and mums show up.
Piedmont Jingle Jam returns Saturday, November 7, from 9 a.m. to 2 p.m. at Piedmont Intermediate School, 977 Washington Ave NW. Same vendor energy as Founders Day, indoors, and timed for people who take Christmas shopping seriously. The Scented Cardinal and other Founders Day regulars typically run both.
If you missed Founders Day sign-ups, Jingle Jam is a smaller, indoor version of the same community. It is also where the crossover happens. Vendors compare notes on which festival was better for them, which is the closest thing Piedmont has to a small-business benchmark.
A note for anyone new to town
If this is your first Founders Day, three unwritten rules matter.
Bring cash. Most vendors take cards now, but the pie raffle, the 5K day-of sign-up, and a handful of the older Junklahoma booths still prefer paper.
Wear layers. September in Oklahoma runs from a 55-degree parade morning to an 85-degree afternoon in the same six-hour window.
Talk to the vendors. Half of them live within ten miles of the church lot. The Scented Cardinal, The Old Store, and the Farmers Market regulars are the people who will tell you which contractor actually finished on time, where to take a broken lawn mower, and which HOA in your part of town runs a good garage sale weekend. That information does not exist on Google, and Founders Day is where it changes hands.
The one-sentence version
Founders Day works best when you treat it as the anchor of a full Saturday on Monroe Avenue, one that starts at the farmers market, moves through 150 vendors and a parade, breaks for lunch at a place that is not a food truck, and ends with the kids at the inflatables while the crowd thins.
That is the version of the day the newest neighbors on your street do not know yet. Send them this. Then find them at the parade.
Piedmont is one of the fastest-growing corners of the Oklahoma City metro, and the community texture around events like Founders Day is a real part of why people put down roots here.
