Fantasy is the fifth album by American singer-songwriter Carole King, released in 1973. At the time of its release, it only reached number six on the US Billboard 200 album chart, but has remained highly regarded by her fans over the ensuing decades. Presented as a sort of song cycle, the album opens and closes with two versions of the title song and the songs on each side segue directly into one another.
