Texas' 26th congressional district of the United States House of Representatives includes rural Cooke County to the north and some of Wise County to the West and includes parts of Denton County, including Flower Mound, Lewisville and parts of Corinth, Carrollton, Little Elm and The Colony.

The district is best known as the seat of former House Majority Leader Dick Armey.

The district was created as a result of the redistricting cycle after the 1980 census, due to the population growth in Texas and Denton County, specifically in its southern sector.

After the 2020 census, rapid growth resulted in significant changes in the composition of the district.

Denton had become increasingly friendly to Democrats in recent years, and voting trends suggested that under the previous map, the 26th could have potentially become competitive.
