Nathaniel Dorsky (born 1943) is an American experimental filmmaker and film editor. His film career began during the New American Cinema movement of the 1960s, when he met his partner Jerome Hiler. He won an Emmy Award in 1967 for his work on the film Gaugin in Tahiti: Search for Paradise.
After moving to San Francisco in the 1970s, Dorsky eventually edited some of his earlier footage to create the 1982 film Hours for Jerome, which was inducted into the United States National Film Registry. Through his short lyric films, he developed the style of polyvalent montage for which he is known. In addition to his own films, Dorsky has worked as an editor or film doctor on other projects, particularly documentaries.
