HMS Euryalus (F15) was a Leander-class frigate of the Royal Navy (RN). Like the rest of the class, Euryalus was named after a figure of mythology. Euryalus was built by Scotts Shipbuilders of Greenock. Euryalus was launched on 6 June 1963, and commissioned on 16 September 1964. This Euryalus was the sixth of the name and had a strong liaison with the Lancashire Fusiliers, whose motto (Omnia Audax) she bore from the 4th Euryalus landing its 1st Battalion at W Beach, Gallipoli, where the Regiment "won six Victoria Crosses before breakfast".
