Donald Hugh "Don" Henley (born July 22, 1947 in Gilmer, Texas, U.S.) is an American rock singer, songwriter and drummer, best known as a founding member of the Eagles before launching a successful Grammy Award winning solo career.

The Eagles were formed in 1971, and released their first album in 1972, which contained the hit song "Take It Easy," as well as Henley's first hit songwriting attempt, "Witchy Woman", co-written with guitarist Bernie Leadon. As the 1970s progressed, Henley's raspy vocals replaced Glenn Frey's smooth tenor as the focal point of the Eagles' sound.

During the band's run, Henley co-wrote (usually with Frey) most of the band's best-known songs, notably "Desperado" and " Hotel California." It was on the album Hotel California that Henley wrote what many consider his masterpiece: "The Last Resort." The song tells the story about the negative impact of the westward movement. Or as he explained it: "...we all know how the west was won. This is a song about how the west was lost!" Henley has always been a supporter for rights of the downtrodden and the Democratic Party.

Henley sang lead vocals on many of the band's popular songs, including "Desperado", "The Best of My Love", "One of These Nights", "Hotel California", "The Long Run", and "Get Over It". The Eagles won numerous Grammy Awards during the 1970s and became one of the most successful rock bands of all time. Their Greatest Hits (1971-1975) is the best-selling album ever (in America), in any category. They are also the only band to have two best-selling albums in the top 15 American best-sellers of all time, and are also amongst the top 5 overall best-selling bands of all time in America.
