The Kortlandse Mill is a historic corn mill in the town of Alblasserdam. The mill was built in the early 18th century. The design of the mill is quite unusual, with a more cylindrical hull than most other mills in the area. The mill was sold to the Foundation for the Conservation of Mills in Alblasserwaard and Vijfheerenlanden in 1986, and extensive restoration work was performed in 1990. Tours of the mill are available by appointment.
