Mikhail Nikolayevich Rumyantsev (Russian: Михаил Николаевич Румя́нцев) (10 December 1901 – 31 March 1983), better known under his stage name Karandash (Russian: Каранда́ш which means pencil), was a famous Soviet clown. He was a People's Artist of the USSR and a Hero of Socialist Labour, and was the teacher of the famous Russian clowns Oleg Popov and Yuri Nikulin.

Starting his career in the circus arena as the imitator of Charlie Chaplin, Mikhail Rumyantsev then abandoned it for, or rather, transformed that part into his would-be renowned image of Karandash always accompanied with his hallmark Scottish Terrier named Klyaksa (which means blot). He enjoyed immense popularity with the Soviet audience and often gathered full houses all over the country. Rumyantsev taught his profession to both Oleg Popov and Yuri Nikulin.
