The Mill No. 2 is an historic polder mill located on Achtermiddenweg in the town of Aarlanderveen. It was built in 1869 to replace an 18th century polder mill that had been destroyed in a fire the previous year. The mill served the old 450 hectare West Aarlanderveen polder. The Mill No. 2 was bought by the Aarlanderveen Mill Foundation in 1963, and is still in use as a polder mill today. The Mill No. 2 is one of four mills in the Aarlanderveen area.
