[6] The land was donated by the Blackland Townsite Company, a subsidiary of the St. Louis and San Francisco Railroad.

Historically, the town center was based near the intersection of two railroads, near present-day East Hebron Parkway and 1st Street.

The town was first incorporated in 1961 as a method to prevent Plano and Carrollton from annexing the territory and imposing taxes.

The city of Hebron imposed no taxes of its own, and when the time was ripe for a landowner to develop his land, he would ask the town to disannex that parcel.

Hebron's city limits once covered about 25 square miles (65 km2) from the Collin County line west to the Trinity River and from the Dallas County line north to State Highway 121.

Now it comprises a few plots of land connected with narrow strips and easements, which confuses many maps.

Air Park-Dallas Airport was built as a public civilian airstrip within the city limits in 1965.

For the last 20 years, Hebron has disannexed large portions of its territory to be annexed by neighboring communities (Lewisville, The Colony, Carrollton, and Plano) instead.

A small, disconnected piece of the town is in southwestern Collin County.
