Hagestedgaard is a manor house and estate located at the village of Hagested, near Holbæk, Holbæk Municipality, some 60 kilometres west of Copenhagen, Denmark. The estate traces its history back to the 13th century but the current asymmetrical complex of single-storey, white-washed buildings surrounding a central courtyard was constructed for Hans Didrik Brinck-Seidelin in 1747 with the exception of the remains of a tower built by Johan Friis in 1555. The estate has been owned by members of the Castenskiold family since 1769.
