Mansfield is located in the south center of the Dallas-Fort Worth area with easy access to all the attractions the metroplex has to offer. It’s minutes to everything—including Dallas Cowboys games, the Fort Worth Stock Show & Rodeo at Dickies Arena, the Dallas Zoo, amusement parks, motorsports, professional and college sports of all kinds, cultural events and fine dining.

However, you don’t have to go far to find family-friendly attractions. Mansfield has over 900 acres of beautiful parks, over 100 athletic fields, a water park, off-roading trails, golf courses, and the nearby 7,700-acre Joe Pool Lake. There’s always something to do in Mansfield—including the annual pickle parade, farmer’s markets, fun runs, music and arts festivals, live theater, and concerts.

Named after the Man and Feild grist mill, the town of “Mansfeild” eventually became known as Mansfield. Today over 73,000 residents are proud to call Mansfield home, and the town has been on Money Magazine’s list of the "Best Places to Live" in America, as well as one of the most affluent cities in Texas.
