Serious Fun is a live album by pianist and composer George Gruntz which was recorded in Switzerland in 1989 and released on the Enja label the following year.

[1][2] The Allmusic review by Scott Yanow stated "George Gruntz is best known as the leader and arranger of his Concert Jazz Band so this trio date is a real rarity.

Gruntz's piano playing, although very much in the tradition, features his own individual voice.

... Gruntz is in excellent form throughout this enjoyable live set".
