John Lyras was a 7,513 GRT heavy lift ship that was built in 1942 as Empire Elaine by Vickers-Armstrongs Ltd, Barrow in Furness, Lancashire, United Kingdom for the Ministry of War Transport (MoWT). She spent most of the Second World War serving in the Indian Ocean, although she did visit the Mediterranean to take part in Operation Husky and Operation Dragoon. In 1947, she was sold into merchant service and renamed John Lyras. In 1959, she was sold to a Panamania owner. A further sale in 1970 saw her renamed Boundary. She served until 1972 when she was scrapped.
