Watermark is the third solo studio album by Art Garfunkel, released in October 1977 on Columbia Records.

The first single, "Crying in My Sleep", failed to chart, but the follow-up, a version of "(What a) Wonderful World" (featuring harmony vocals from Garfunkel's old partner Paul Simon and mutual friend James Taylor) reached #17 on the Billboard Hot 100 chart and #1 on the Adult Contemporary chart.

The songs "Watermark" and "Paper Chase" had previously been performed by Richard Harris on his albums A Tramp Shining and The Yard Went On Forever.

Watermark is also noted as being the final recording sessions of legendary saxophonist Paul Desmond who died of lung cancer shortly thereafter.

Actress Laurie Bird, Garfunkel's girlfriend, made the album cover's photograph.
