Hook and Ladder No. 4

Hook and Ladder No. 4, originally Truck No. 4, is a firehouse located at Delaware Avenue in Albany, New York, United States. It is an elaborate brick structure in the Dutch Colonial Revival architectural style, designed by Albany architect Marcus T. Reynolds, and completed in 1912. In 2001 it was listed on the National Register of Historic Places.

It is one of Reynolds' few public buildings, and one of the rare uses of the Dutch Colonial Revival in a city established by Dutch colonists in the late 17th century. In addition to its distinctive stepped gable, the building also features terra cotta sculptures that illustrate Albany's history. Its construction reflected the city's expansion in the early 20th century, and it has remained in use as a firehouse.
