Anne Cathrine Collett (19 February 1768 – 27 January 1846), was a Norwegian-Danish landowner and one of the wealthiest women of Denmark in her time.

Collett was born into the wealthy Collett family of timber merchants in Christiania (now Oslo). Her parents were Peter Collett (1740–86) of Buskerud and Maren Kirstine Holmboe (1745–68). She married Peter Nicolaj Arbo who subsequently entered the family's company Collett & Søn.{{cite web|url=http://gladsaxelokalhistorie.dk/index.php/1550739|title=Bondegård - pensionat - rådhus - gæstehus|language=Danish|website=Gladsaxe Lokalhistoriske Forening|accessdate=17 January 2017|archive-url=https://web.archive.org/web/20170823022452/http://gladsaxelokalhistorie.dk/index.php/1550739|archive-date=23 August 2017|url-status=dead}}

The couple moved to Copenhagen where they lived in the Peschier House at Holmens Kanal 12. He acquired the country house Aldershvile north of Copenhagen and the manors of Lundbygård and Oremandsgaard at Præstø. After his death in 1827, she ran the estate with the assistance of count Knuth.

Collet died on 27 January 1846. Having no children, she left her estate to her nephews Bernt Anker Collet and Peter Collet (1820-1860).
