El Mirage is the sixth album by American singer-songwriter Jimmy Webb, released in May 1977 by Atlantic Records. This was the second album for which Webb handed production and arrangement duties on to another person, George Martin, producer of the Beatles. The album contains "The Highwayman", a song that later provided both the name and first hit for the Highwaymen. Waylon Jennings, part of the Highwaymen, also recorded the track "If You See Me Getting Smaller" for his album Ol Waylon (1977). The cover was photographed at El Mirage Lake, Mojave Desert, California.

In his review for AllMusic, William Ruhlmann called the album Webb's "most polished effort yet as a performer". Ruhlmann noted the "lush tracks full of tasty playing and warm string charts". He described the re-recording of "P.F. Sloan" as "unnecessary", but found the compositions generally up to Webb's high standard as a songwriter, and the album as a whole a successful reintroduction of Webb as a pop artist.

All tracks are written by Jimmy Webb, except where noted.
