Dennis Jensen is a comic book artist.

He entered the industry in the late 1970s, working for DC Comics on their Adventure Comics line, inking Carmine Infantino's work, often colored by "Gaff". He also worked on several other titles including The Flash (again with Infantino), Action Comics, and Marvel's Marvel Comics Presents before going into semi-retirement from the industry in the late 1990s.

He illustrated three articles for "Who's Who in Star Trek 2": Areel Shaw, Starbases, and Vians, all with Ken Penders.
