"Believe in Me" is the title of a popular song from 1984 written and recorded by the American singer-songwriter Dan Fogelberg. When "Believe in Me" was recorded in May 1983, Fogelberg handled most of the musical creation himself, playing guitar and bass as well as recording his vocals; musician Mike Hanna (who played acoustic guitar on the track) was the only other performer in the studio. Fogelberg later described the song in the liner notes to a retrospective album: "One of my best love songs. Written at my old house in Nederland, Colorado, while building the ranch. Obviously, all was not well."

Released as the second single from Windows and Walls, "Believe in Me" missed the Top 40 of the Billboard Hot 100 chart, where it peaked at #48. However, on the Billboard adult contemporary chart, where Fogelberg had enjoyed more consistent success, the song became his fourth #1 hit, following his earlier singles "Longer", "Leader of the Band", and "Make Love Stay"
