Lieutenant-Colonel Sir Roland Vaughan Gwynne DSO, DL, JP was a British soldier and politician who served as Mayor of Eastbourne, Sussex, from 1928 to 1931. He was also a patient, close friend, and probable lover of the suspected serial killer Dr John Bodkin Adams.

John Bodkin Adams was a British general practitioner, convicted fraudster, and suspected serial killer. Between 1946 and 1956, 163 of his patients died while in comas, which was deemed to be worthy of investigation. In addition, 132 out of 310 patients had left Adams money or items in their wills.
