Huis Honselaarsdijk (English: "House Honselaar's Dike") was a palace in Honselersdijk, Holland, Dutch Republic. The palace was designed by the Dutch architects Jacob van Campen and Pieter Post, and was built in the first half of the 17th century as a buitenplaats for stadtholder Frederick Henry, Prince of Orange.
After the death of king-stadtholder William III, the palace was neglected and its main building was demolished in 1815. De Nederhof, one of two additional buildings used as guest quarters, still remains and is now a home for people with disabilities.
