Donald Edwin Young was an American politician in Alaska. He was the longest-serving Republican in House history, having been the U.S. representative for Alaska's at-large congressional district for 49 years, from 1973 until his death in 2022.

Since becoming a U.S. state in 1959, Alaska has been entitled to one member in the United States House of Representatives, elected in the state's sole, at-large congressional district. By area, Alaska's congressional district is the largest congressional district in the United States and the third-largest electoral district represented by a single member in the world, behind only Yakutsk district in Russia and Nunavut's sole electoral district in Canada.
