Beat Space Nine is the fourth studio album released by the Japanese group M-Flo.

The record is presented in the metaformat of a spaceliner's in-flight entertainment system, specifically that of "Global Astroliner", constituting a recurring theme in the group's albums.

By the end of the year, the album sold over 334,000 copies and was certified platinum by the Recording Industry Association of Japan (RIAJ).

Vocalist Lisa, who was previously a member of M-Flo, appears on the second to last track of this album, "Tripod Baby".

The track "Tripod Baby" was remixed as a promotional song for the Shadow the Hedgehog video game released in November 2005.
