120 Minutes is a television show in the United States dedicated to alternative music, originally airing on MTV from 1986 to 2000, and then on MTV's sister channel MTV2 from 2001 to 2003.

After its cancellation, MTV2 premiered a replacement show called Subterranean. A similar but separate VH1 Classic program, VH1 Classic 120 Minutes, plays many classic alternative videos that were regularly seen on 120 Minutes in its heyday.

120 Minutes returned as a monthly series on MTV2 on July 30, 2011, with Matt Pinfield as host.
