Tore Eckhoff Deinboll (July 12, 1910 – November 18, 1988) was a Norwegian artist, cartoonist, and illustrator.
Deinboll was born in Oslo, the son of the patent attorney August Deinboll (1880–1975) and the teacher Anna Hermine Eckhoff (1884–1967), and was later the stepson of the librarian Rikka Deinboll (1897–1973). He studied in the painting program at the Norwegian National Academy of Fine Arts. There he became acquainted with several artists, including Kaare Espolin Johnson, the brothers Olav and Trygve Mosebekk, and Edvarda Lie. Deinboll became especially good friend with Espolin Johnson.
As a cartoonist, Deinboll was known for the comics Den evige ilds land (The Land of Eternal Fire, 1936–1937) and Petter Framgutt (1938). Both series were published as weekly full-page works in the magazine Arbeidermagasinet.
