Jørgen Jacob Scheel (born Randers Municipality 9 February 1916, died 13 April 1989) was a Danish aristocrat, soldier, explorer and ichthyologist.
His father was Jørgen Carl Scheel (1874-1944) and his mother was Erikka Ellen Estrup (1891-1960); his parents married in 1912.
In 1954 he was a Kaptajn in the Guards and he ended his military career as an Oberst in command of Denmark's Defence Motor School.
He did much to promote the hobby of fish keeping in Denmark and beyond and wrote a number of books on the subject.
On these expeditions Scheel discovered many new species of fish, especially killifishes, which he described.
