Kiyohiko Azuma (born May 27, 1968, in Takasago) is a Japanese manga writer and illustrator. He is famous for writing the manga series Azumanga Daioh, serialized from 1999 to 2002 in the Monthly Comic Dengeki Daioh magazine. His current series is Yotsuba&!, also serialized in Dengeki Daioh. In his manga, he writes under the hiragana form of his name, which has led some non-Japanese-speakers to confuse him for a woman (as they have mistaken the masculine ending -hiko for the feminine -ko)
