The landing craft mechanized (LCM) is a landing craft designed for carrying vehicles. They came to prominence during the Second World War when they were used to land troops or tanks during Allied amphibious assaults.
 
There was no single design of LCM used, unlike the landing craft, vehicle, personnel (LCVP) or landing craft assault (LCA) landing craft made by the US and UK respectively. There were several different designs built by the UK and US and by different manufacturers.
