ARA King is a World War II-era Argentine Navy warship, originally classified as minelayer and later as patrol ship.

The vessel is named after Juan King, an Argentine naval officer that served in the Cisplatine War.

Two (Murature and King) were completed as patrol boats and the others (Piedrabuena and Azopardo) as antisubmarine frigates.

In 1955, the ship took part of rising against Juan Domingo Perón's government known as Revolución Libertadora, when she acted as a floating battery defending the rebel naval base at Río Santiago.
