Austin is divided among six U.S. congressional districts: the 10th, 17th, 21st, 31st, 35th, and 37th. Because these lines cut through neighborhoods and split suburbs like Pflugerville, Round Rock, Cedar Park, Kyle, and Buda across two or three districts each, next-door neighbors can have different representatives in Washington. The only reliable way to know which of Austin’s congressional districts covers your home is an address-level lookup, but the shape of each district and its current representative will tell you what to expect once you find yours.
How to Find Your District by Address
Start with the Texas Legislature’s “Who Represents Me?” page. You enter your home address and see every elected official who represents you, from your U.S. Representative down to your state legislators.1Texas Capitol. Who Represents Me? The U.S. House also runs a national “Find Your Representative” tool that works by ZIP code or address; if your ZIP spans multiple districts, it will prompt you for a full street address.2U.S. House of Representatives. Find Your Representative
If you have moved anywhere in the Austin area, even a short distance, check whether you crossed a district line. A move between districts means a new representative, and you are required to update your voter registration with your new address. You can update online, by mail, or in person at your county election office.3USAGov. How to Update or Change Your Voter Registration
The Six Districts and Who Represents Them
The descriptions below give the general shape of each district. They are not a substitute for the address lookup, because so many communities sit right on a boundary.
37th District: Central Austin
The 37th is the most compact of the six, centered on the urban core of Travis County. It covers downtown, the University of Texas campus, and the dense central neighborhoods on both sides of Interstate 35, along with West Lake Hills, Rollingwood, Sunset Valley, San Leanna, and portions of Pflugerville.4Texas Department of Transportation.

35th District: The I-35 Corridor to San Antonio
The 35th follows I-35 south from Austin, covering southern and eastern Travis County and parts of Hays, Caldwell, Comal, and Guadalupe Counties. It takes in Buda, parts of Kyle, San Marcos, stretches of New Braunfels, and San Antonio’s northeastern suburbs including Converse, Schertz, and Live Oak.6U.S. Census Bureau.

10th District: Northeast Toward Houston
The 10th covers portions of northeastern Travis County and extends east through rural Central Texas toward the Houston suburbs, making it one of the more geographically stretched districts touching Austin. Michael McCaul (Republican) is the current representative and announced in September 2025 that he will not seek another term, serving through the end of the 119th Congress in January 2027.14McCaul.

Key Dates for the 2026 Election
Every House seat is on the ballot in 2026. The Texas primary is March 3, 2026, with a primary runoff on May 26, 2026, for any race where no candidate wins a majority.15Texas Secretary of State.

Texas requires voter registration at least 30 days before any election. For the March 2026 primary, the deadline is February 2, 2026.17VoteTexas.gov.

If you live in either district, the primary is where the field narrows.
What Your Representative’s Office Can Do
Knowing your district is more than a civics detail. Your U.S. Representative’s office provides direct help with federal agencies when you cannot get a response on your own. If you are stuck waiting on a passport, cannot reach the IRS, need help with Social Security or veterans’ benefits, or are tangled with any federal bureaucracy, the office’s constituent services staff can intervene. You will typically sign a privacy release form authorizing the office to contact the agency about your case.
Congressional offices also handle requests many constituents do not know to ask about. You can order an American flag flown over the U.S. Capitol, with a personalized certificate, through your representative’s office. If you are planning a trip to Washington, the office can help arrange tours of the Capitol, the White House (request at least three months in advance), and the FBI headquarters. Each Austin-area representative maintains a local district office as well as their Washington office, so you do not need to travel to D.C. for help.
