Affinity is an album by American jazz pianist Bill Evans released in 1979, featuring Belgian harmonica player Toots Thielemans.

Bill Evans plays a Rhodes piano on many of the tracks.

It is the recording debut for bassist Marc Johnson.

With the exception of a four star Rolling Stone Jazz Record Guide review,[1] the majority of recorded reception for the Affinity album came significantly later than its original release.

Scott Yanow on Allmusic says, "Excellent if not essential music that Evans generally uplifts".
