Prior to the existence of Mabank in early 1900, the community of Lawndale was formed in the late 1880s. The community was noted for its agriculture in many areas, including cotton. But with the Texas Trunk Railroad missing the community by a mile, Ranchers Mason and Eubank decided to capitalize on the Texas Trunk and set aside one square mile of land and named it "Mabank".
Mabank is a combination of the names Eubank and Mason and is located one mile (1.6 km) southwest of the former community of Lawndale. Being only a mile away from Lawndale and located on the railroad, its citizens, churches, and businesses naturally decided to move there.
