The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M series up to the current film Leica M7 and digital Leica M.

This lens mount has also been used by Minolta on the Minolta CLE rangefinder camera, by Konica on the Hexar RF, by Voigtländer (Cosina) on the late models of the Bessa range, by Rollei on the Rollei 35RF and very recently by Zeiss Ikon on the latest Zeiss Ikon rangefinder camera and by Ricoh in the GXR system.
