The Handboogdoelen is a building on the Singel canal in Amsterdam, near Koningsplein square. It dates back to the early 16th century and originally served as headquarters and shooting range of the local schutterij. Most of the current building at Singel 421 dates to the 18th century and is part of the main complex of the Amsterdam University Library. The Doelenzaal hall on the ground floor of the building is used for lectures, meetings, receptions and doctoral dissertations. The building has rijksmonument status.
