Fool on the Hill is the fourth studio album by Sérgio Mendes and Brasil '66, released in 1968.

This is the first album featuring the second edition of Brasil '66. Mendes replaced all of the original band members (with the exception of lead singer Lani Hall). The dismissed members went on to form the short-lived group, The Carnival, which released one self-titled album in 1969. This is also the first appearance of Gracinha Leporace on a Sérgio Mendes album.

The album features two top 10 pop singles: the title track and "Scarborough Fair". The traditional English folk song (covered notably by Simon & Garfunkel) was featured in both the trailer and the soundtrack for the 1973 film Heavy Traffic.
