Maréchal des logis (French for 'marshal of lodgings') is a sub-officer rank used by some units of the French Armed Forces.

There are three distinct ranks of maréchal des logis, which are generally the equivalents of sergeant ranks (although they generally have less responsibility than a British or Commonwealth sergeant).

The maréchal des logis usually commands a section, tank, or gun, and therefore corresponds approximately to the British or Commonwealth rank of corporal, the U.S. Army rank of staff sergeant, or the U.S. Marine Corps rank of sergeant.

The rank of maréchal des logis is used by the armoured cavalry, the artillery, the materiel, the commissary and the transport corps, all of the French Army, and by the Gendarmerie Nationale.

The term logistics is derived from maréchal des logis, by Antoine-Henri Jomini.
