Bob de Moor is the pen name of Robert Frans Marie De Moor (20 December 1925 – 26 August 1992), a Belgian comics creator. Chiefly noted as an artist, he is considered an early master of the Ligne claire style. He wrote and drew several comics series on his own, but also collaborated with Hergé on several volumes of The Adventures of Tintin. He completed the unfinished story Professor Sató's Three Formulae, Volume 2: Mortimer vs. Mortimer of the Blake and Mortimer series, after the death of the author Edgar P. Jacobs.
