The Best of Simon and Garfunkel is the fifth compilation album of greatest hits by Simon & Garfunkel, released by Columbia Records in 1999, containing 20 tracks.

Old Friends is the second box set of Simon & Garfunkel songs, released in November 1997. The three-disc anthology collects most of the duo's best-known works, and also includes previously unreleased outtakes. Some of these outtakes subsequently appeared on both the reissues of Simon & Garfunkel's five studio albums as well as the later boxed set The Columbia Studio Recordings (1964-1970).
