Caught in the Act is a live double album by Styx, released in 1984.

It contains one new song, "Music Time," which was released as a single, reaching #40 on the Billboard Hot 100 charts.

Caught in the Act is also the name of a VHS video recording that featured the band acting out the concept established in their Kilroy Was Here album.

Shortly after this album's release, Tommy Shaw announced his departure from the band to pursue a solo career.

Caught In The Act would ultimately prove to be the final album by the massively successful 1975-84 Styx lineup of Dennis DeYoung, Shaw, James Young, Chuck Panozzo, and John Panozzo; by the time Shaw returned to the band in 1995, John Panozzo's declining health prevented his participation, and he died in 1996.
