Anders Beer Wilse (12 June 1865 – 21 February 1949) was a Norwegian photographer who documented Norway in the early to mid-20th century and also worked in the United States.

In 1900, his wife and children moved to Norway, and Wilse himself joined them, opening a photography store in Christiania in 1901, after 17 years in the United States.

He photographed both natural sceneries and people at work, including the fishing industry in Lofoten before the introduction of motorized boats.

His photography business was also a commercial success, and he acquired among other things the entire archive of Axel Lindahl, who had photographed scenes in Norway in the 1880s and 1890s.

Most of his negatives are now preserved at museums, including Norsk Folkemuseum, where more than 100,000 sceneries and ethnological images are held, Oslo Bymuseum for images related to the history of Oslo, the National Library of Norway for portrait photography, and the Norwegian Maritime Museum for maritime photographs.
