James Houston Davis (September 11, 1899 – November 5, 2000) was an American singer, songwriter, and Democratic Party politician. After achieving fame for releasing both sacred and popular songs, Davis served as the 47th governor of Louisiana from 1944 to 1948 and again from 1960 to 1964.

Davis was a nationally popular country music and gospel singer from the 1930s into the 1960s, helping country music gain appeal beyond the rural southern U.S. and occasionally recording and performing as late as the early 1990s. His most popular song, a cover of "You Are My Sunshine", was released in 1940 and would become Louisiana's official state song. He appeared as himself in a number of Hollywood movies. He was inducted into six halls of fame, including the Country Music Hall of Fame, the Southern Gospel Music Association Hall of Fame, and the Louisiana Music Hall of Fame.

First elected in 1944, Davis served two non-consecutive terms as governor of Louisiana, during which he implemented the first driver's licensing, public employee pension, and civil service systems in Louisiana and opposed desegregation. At the time of his death in 2000, he was the oldest living former governor as well as the last living governor to have been born in the 19th century.
