Power in Numbers is the third studio album by American hip hop group Jurassic 5, released on October 8, 2002, by Interscope Records.

It picks up where their previous album, Quality Control "left off", with a short double bass sample playing the same riff that the last song on Quality Control, "Swing Set", ended with.

One track, "React", composed by Jurassic 5 DJ Cut Chemist, is sample-based and contains no raps.

"A Day at the Races" is based around a sample of David Axelrod's "Urizen" from the album Song of Innocence.

Many tracks start or end with a sample of speech, usually inserted by Cut Chemist.
