Noboru Baba (馬場のぼる, Baba Noboru; October 18, 1927 – April 7, 2001) was a Japanese manga artist and writer. He is best known for his long-running four-panel newspaper comic Baku-san and for the acclaimed children’s picture book series 11 Piki no Neko (Eleven Cats). Active from the postwar period through the late 20th century, Baba was often referred to as one of the “Three Crows of Children’s Manga,” alongside Osamu Tezuka and Eiichi Fukui.
