Texas's 3rd congressional district is a United States House of Representatives district in suburban and some rural areas north and northeast of Dallas. It encompasses much of Collin County, namely McKinney and Allen, as well as parts of Plano, Frisco, and Prosper. Additionally, the district includes all but the southern portion of Hunt County. The district is also home to a public four-year university, East Texas A&M University, as well as most of the Collin College campuses.

Texas has had at least three congressional districts since 1869. The current seat dates from a mid-decade redistricting conducted before the 1966 elections after the case Wesberry v. Sanders voided Texas's original, pre-1960s map. In past configurations, it has been one of the most Republican districts in both Texas and the Dallas–Fort Worth metroplex. The GOP has held the seat since a 1968 special election; the district's current congressman is Keith Self.

As of the 2010 census, the 3rd district represents 765,486 people who are predominantly middle-to-upper-class (median family income is US$80,912). The district is 59.1 percent non-Hispanic White, 15.06 percent Hispanic or Latino (of any race), 13 percent Asian, and 8.9 percent Black or African American.

From 1967 to 2013, the 3rd district included large portions of Dallas County. Eventually, it covered much of northern Dallas County, including Garland, Rowlett, and much of northern Dallas itself before it pushed into Collin County in 1983. Since then, Collin County's rapid growth resulted in the district's share of Dallas County being gradually reduced. After redistricting in 2012, the Dallas County portion of the district was removed altogether. However, it still included the Dallas precincts located in Collin County.

2021 redistricting From 2013 to 2021, the district represented suburban areas north and northeast of Dallas. It encompassed much of Collin County, including McKinney, Plano, and the majority of Frisco, as well as a portion of the city of Dallas. The district was also home to the public Collin College, and the Frisco campus of the University of North Texas.

After redistricting in 2021, the Dallas and Richardson portions of the district were removed, as well as much of Plano and Frisco. The Richardson portion of the district was transferred to District 32, while the Plano, Dallas, and Frisco portions went to District 4. In return, District 3 was expanded eastward to encompass most of Hunt County.
