'''Karl Fabel''' (October 20, 1905 in [[Hamburg]] – March 3, 1975 in [[Egenhofen]]) was a German [[chess composer]].

Fabel received a doctorate in [[chemistry]] and worked as a [[mathematician]] and civil judge at the federal office of brands and patents in Munich, of which he was also president.

He is considered one of the most ingenious chess composers and one of the fathers of [[retrograde analysis]], frequently collaborating with {{ill|Luigi Ceriani|it}} in this area. He composed around 1250 problems of all varieties. He studied chess problems of a mathematical nature such as the [[Eight queens puzzle]], the [[Knight's tour]] and [[Shannon's number]]. He was a director of [[Die Schwalbe]].
