Bernt Anker (22 November 1746 – 21 April 1805) was a Norwegian merchant, chamberlain and playwright.
He was born in Christiania; the son of Christian Ancher, brother of Peder Anker and cousin of Carsten Anker. His business included trade in timber on large scale, with a large income from supplying the fleet of England. He eventually became the wealthiest person in Norway. Among his properties were Frogner Manor and Moss Jernverk. His magnificent home Paléet near Bjørvika was used as a Royal residence after his death, until the completion of the Royal Palace in Christiania.
