Oklahoma's 3rd congressional district is the largest congressional district in the state, covering an area of 34,088.49 square miles, over 48 percent the state's land mass. The district is bordered by New Mexico, Colorado, Kansas, and the Texas panhandle. Altogether, the district includes (in whole or in part) a total of 32 counties, and covers more territory than the state's other four districts combined. It is one of the largest districts in the nation that does not cover an entire state.

The district has been represented by Republican Frank Lucas since 2003.

Prior to 2003, most of the territory now in the 3rd district was in the 6th district. Meanwhile, from 1915 to 2003, the 3rd district was located in southeastern Oklahoma, an area known as Little Dixie. It had a dramatically different voting history from the current 3rd; only one Republican ever won it. It was the district of Carl Albert, Speaker of the House from 1971 to 1977.
