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, the majority of recorded reception for the Affinity album came significantly later than its original release. Overall, reviewers maintain positive notes about the work. Scott Yanow on Allmusic says, "Excellent if not essential music that Evans generally uplifts".
