The Impossible Dream is a double compilation album by American pop singer Andy Williams that was released in late 1971 by Columbia Records. Unlike his most recent compilation, Andy Williams' Greatest Hits, this 2-LP set focused exclusively on covers of songs made famous by other artists and included four tracks ("He Ain't Heavy, He's My Brother", "The Last Time I Saw Her", "Long, Long Time", and "Someone Who Cares") that had previously only been available on his UK album titled Love Story. In 2003 these tracks were released on the Williams collection from Collectables Records titled B Sides and Rarities.
The album made its first appearance on Billboard magazine's Top LP's chart in the issue dated January 8, 1972, and remained there for five weeks, peaking at number 123, and it entered the UK album chart three months later, on April 29, and reached number 26 there over the course of three weeks.
