Andreas Dettloff (born 26 October 1963) is a German visual artist who lives and works in Tahiti. He is one of the most influential artists in French Polynesia.
Dettloff was born in Iserlohn in Germany and educated at the Kunstakademie Düsseldorf. He was awarded a scholarship allowing him to travel to Australia, Easter Island and Polynesia. In 1989 he settled permanently in Tahiti.
Dettloff uses traditional Polynesian symbols, which he mixes with those of the western world. He was probably the first artist to introduce sometimes conceptual art into Polynesia.
