Third Monday Trade Days in McKinney, Texas is the oldest and largest monthly trade days/flea market in North Central Texas. Located in a historic area of Collin County amid trees and a creek, TMTD is less than an hour’s drive from Dallas and Fort Worth.

Over 450 vendors offer almost anything you can imagine—unique gifts, delightful home décor, trendy clothing and accessories, sporting goods, antiques and collectibles, landscaping materials, tools, and small animals along with many specialty “state fair” type food concessions.

Shoppers will find plenty of all-weather parking, clean restrooms, two ATMs, an air conditioned and heated Mall building, mobility scooter rental, wagon and stroller rental, and a family-friendly atmosphere including a fun playground, train ride, and pony ride.

Third Monday is open year-round from 8 a.m. to 5 p.m. on the Friday, Saturday, and Sunday before the third Monday of each month. Admission is free and parking is free all day on Friday and after 3 on Saturday & Sunday ($5 at other times). See the Market Schedule for this year’s dates.
