45 Commando Royal Marines (pronounced "four-five commando") is a battalion sized unit of the British Royal Marines and subordinate unit within 3 Commando Brigade Royal Marines, the principal Commando formation, under the Operational Command of Commander in Chief Fleet.

Tasked as a Commando amphibious unit, 45 Cdo RM is capable of a wide range of operational tasks. Based at RM Condor, their barracks in Arbroath, personnel regularly deploy outside the United Kingdom on operations or training. While 3 Cdo Bde RM are the principal cold weather warfare formation, personnel are capable of operating in a variety of theatres including tropical jungle, desert or mountainous terrain. The Commando is a regular participant in the annual Brigade cold weather warfare exercise in Norway, having been the first UK unit to specialise in the mountain and Arctic warfare role during the early 1970s and deployed to Norway on NATO’s northern flank most years until the end of the Cold War.

All personnel have completed the Commando course at the Commando Training Centre(CTCRM) at Lympstone in Devon, entitling them to wear the green beret, with attached personnel having completed the All Arms Commando Course.

The 5th RM Battalion was originally raised for a brief period at the end of World War I (September 1918-February 1919), and was again raised on 2 April 1940 following mass mobilisation and the influx of “hostilities only” (HO) marines. The battalion was raised at Cowshot Camp in Brookwood (now part of the Pirbright Camp complex), being incorporated into 101 RM Bde, along with the 1st RM Battalion. Between August and October 1940 the battalion took part in operations in Dakar. On return until August 1943 the battalion conducted extensive training in Wales, Scotland, the Isle of Wight and Burley, where the battalion reformed as 45 RM Commando on 1 August 1943.
