LÉ Róisín (P51) is the lead ship of her class of offshore patrol vessel in the Irish Naval Service. Commissioned in 1999, the ship's primary mission is fisheries protection, search and rescue, and maritime protection operations, including vessel boardings. Róisín or Róisín Dubh, is often used as an allegory for Ireland. However, the original Róisín Dubh was a daughter of Red Hugh O’Neill, Earl of Tyrone in the late 16th century.
