The Alkmaar class is a ship class of fifteen minehunters that were built in the Netherlands for the Royal Netherlands Navy. They are based on the design of the Tripartite class, which was developed by a collaborative effort between the Netherlands, Belgium and France, and replaced the minesweepers and minehunters of the Dokkum class.
