HMCS Somers Isles was a temporary training facility and stone frigate for the Royal Canadian Navy (RCN) in Bermuda from 1944 to 1945 during the Second World War. Following the war, the base was closed. Beginning in mid-1944, work-up training for naval ships stationed on the East Coast of Canada took place in Bermudan waters as it allowed for training year-round compared to the RCN's previous work-up site, St. Margaret's Bay and Pictou, Nova Scotia.
