James David Matheson is an American politician who served as a United States Representative from Utah from 2001 to 2015. He represented Utah's 2nd district from 2001 to 2013 and its 4th district from 2013 to 2015 as a member of the Democratic Party. While in office, he was Utah's only congressional Democrat, and his district was one of the most Republican-leaning districts to be represented by a Democrat.

Utah's 4th congressional district is a congressional district created by the state legislature as a result of reapportionment by Congress after the 2010 census showed population increases in the state relative to other states. Prior to 2010 reapportionment, Utah had three congressional districts.
