Family Force 5 (often abbreviated FF5, formerly known as The Phamily and The Brothers) is a Christian Rapcore band from Atlanta, Georgia.

The three leading members of the band, Solomon, Jacob and Joshua, are all three sons of Jerome Olds, a Christian artist from the late 1980s. Growing up around music, the Olds brothers have been involved in it since a very young age.

Family Force 5 uses elements of Rap, Post-hardcore, and club oriented Crunk. The band often cites their own style as Crunk rock. Most songs contain heavy use of synthesizers and simple power chord riffs. Some songs make references to break dancing, the fact that they grew up in Atalanta, and the song Supersonic spells out the word Crunk in the lyrics.
