Bakkehuset is a historic house museum on Rahbeks Allé in the Frederiksberg district of Copenhagen, Denmark. Dating from the 1520s, it has served a number of functions over the years, including as a farmhouse, inn, private home, psychiatric hospital and orphanage. It is particularly associated with the Danish Golden Age when it was owned by Knud Lyne Rahbek and his wife, Kamma Rahbek, used it as a venue for her salons.
