Heavy mortars are large-calibre mortars designed to fire a relatively heavy shell on a high angle trajectory. Such weapons have a relatively short range, but are usually less complex than similar calibre field artillery.

This category includes the "Trench Mortars" of World War I which were all too heavy and cumbersome, and hence lacked the mobility, to be classed as infantry mortars.
