Det Harboeske Enkefruekloster (English: Harboe's Refuge for Widowed Ladies) is a Late Baroque building on Stormgade in Copenhagen, Denmark.

The lot was originally acquired by landdrost Simon de Pethum when Stormgade was created together with the rest of the new Frederiksholm neighbourhood.

Eilersen died in 1708 and in 1711 the wealthy couple extended the house in Stormgade with the assistance of Elias David Häusser who had also designed the 1st Christiansborg Palace.

In 2000, Realdania Byg took over the heavily neglected building and put it through a major renovation under the direction of Jens Baumann.
