Admiral of the Fleet Michael Cecil Boyce, Baron Boyce, KG, GCB, OBE, DL (born 2 April 1943) is a retired senior Royal Navy officer who now sits as a crossbench member of the House of Lords.

Boyce commanded three submarines and then a frigate before achieving higher command in the Navy and serving as First Sea Lord and Chief of the Naval Staff from 1998 to 2001 and then as Chief of the Defence Staff from 2001 to 2003. As Chief of Defence Staff he is believed to have had concerns about US plans for a national missile defence system. In early 2003 he advised the British Government on the deployment of troops for the invasion of Iraq, seeking assurances as to the legitimacy of the deployment before it was allowed to proceed.
