Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Tennessee's 3rd congressional district, as drawn for the 2026 elections, takes in Hamilton, Bradley, Anderson, Roane, and McMinn counties. About 767,800 people live within its 2026 boundaries, with a median age of 40.9. Measured on those boundaries, the district has voted Republican in every presidential election since 2012, by widening margins. The margin was R+29.2 in 2012, R+35.0 in 2016, R+31.7 in 2020, and R+35.7 in 2024.
Across the recorded series it reached a Democratic high of 20.4 points in 1912 and a Republican high of 43.3 points in 1972. Between 2020 and 2024 the district moved 4.0 points toward the Republican candidate; the 2024 margin was 35.7 points.
A population of 767,753, a 78% non-Hispanic-white share, and a median household income of $69,771 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 3 and Congressional District 1.
