The Roberts class of monitors of the Royal Navy consisted of two heavily gunned vessels built during the Second World War. They were the Roberts, completed in 1941, and Abercrombie, completed in 1943.

Features of the class were two 15-inch guns in a twin turret, shallow draught for operating inshore, broad beam to give stability (and also resistance to torpedoes and mines) and a high observation platform to observe fall of shot.
