Irish Shipping Limited was an Irish state-owned deepsea shipping company formed during World War II for the purpose of supplying the country's import needs. Its ships were usually named after trees. Its contribution to Irish neutrality was recognised by the government after the war. In the post-war years the company continued to operate as a commercial strategic reserve until 1984 when as a result of taking on a series of expensive long-term time charters it was forced into liquidation.
