Infinite Joy is a musical revue consisting of songs by Broadway composer William Finn.

The revue was initially performed on various dates in September 2000 and December 2000 through 2001 at Joe's Pub, a nightclub within The Public Theater in New York City.

[3] William Ruhlmann, reviewing the recording for Allmusic wrote: "Finn's songs often have an "inside baseball" quality to them, revolving around the gay, Jewish world of musical theater.

Performers included Betty Buckley, Stephen DeRosa, Raúl Esparza, Jesse Tyler Ferguson and Janet Metz.

The songs were from Finn's The 25th Annual Putnam County Spelling Bee, Elegies, Falsettos, and A New Brain.
