The Yarrow Later M class were a class of seven destroyers built for the Royal Navy that saw service during World War I. They were based on the preceding and successful Yarrow M class with minor alterations; notably reduced beam to compensate for increased displacement and a sloping stern. They were sometimes described as the Yarrow R class of destroyers.
