"Good Time" is a song written by Brian Wilson and Al Jardine for the American rock band the Beach Boys. The instrumental track and vocals were recorded by the group in early 1970 but was left unreleased by the group until the 1977 album Love You. In 1972 American pop duo American Spring released "Good Time" as their second single, recording their voices atop the Beach Boys' instrumental track.

The basic track for "Good Time" was first recorded by the Beach Boys on January 7, 1970 at Brian Wilson's home studio with horns and strings overdubbed at a later date.David Sandler remembers that when the session players arrived to Wilson's home, "he went to his office and wrote horn charts while talking to me. It was an amazing horn line, with this overriding French horn riff, and he did the whole thing while having a conversation with me." The track was included on the provisional track listing for Add Some Music, but when that album and Reverberation were reconfigured by Warner Bros. Records into Sunflower, "Good Time" was not included.

In the second quarter of 1972, Marilyn Wilson of American Spring overdubbed a lead vocal atop the backing track and backing vocals from the Beach Boys' 1970 session with further work done by producers Brian Wilson, David Sandler and Stephen Desper. This version of Good Time was issued as a single on May 1, 1972 and was later included on their début album Spring.

An early take of "Good Time" reportedly features either Brian or Bruce Johnston seguing into a piano rendition of the Beatles' "You Never Give Me Your Money".
