100cc - Greatest Hits of 10cc

100cc is a compilation album by the English rock band 10cc.

It was released in 1975 by UK Records, the band’s original label, to capitalize on the then 10cc’s recent departure to Mercury Records and band’s success in the immediate aftermath of the release of their third album, The Original Soundtrack, and the “I’m Not in Love” single.

The UK edition of the compilation contains a selection of singles on the first side, while the second side contains all of the non-album b-sides from the first two albums' singles.
