Petronella Dunois (1650–1695) was a Dutch art collector, known for her dollhouse in the Rijksmuseum in Amsterdam.

[1] In that year, Dunois married the Leiden regent Pieter van Groenendijck.

[1] Besides the dollhouse, her list contained other costly items such as linens and stock options.

[2] According to the woman who donated the dollhouse in 1934, it was originally in the collection of the admiral Michiel de Ruyter.

The Amsterdam historian Isabella van Eeghen tried to prove this in her 1953 article about the dollhouse, but this was later disproved by Fock, though the donor was indeed a descendant of De Ruyter.
