Buddha is a manga drawn by Osamu Tezuka and is Tezuka's unique interpretation of the life of Gautama Buddha, the founder of Buddhism. The critically acclaimed series is often referred to as a visually explicit yet humorous and thought-provoking portrayal of the Buddha's life. The series began in September 1972 and ended in December 1983, as one of Tezuka's last epic manga works.

Buddha received the 2004 and 2005 Eisner Award. As of early 2006, each volume had sold an average of 8,500 copies, with the first volume, Kapilavastu, having sold 20,000 copies. Due to differences between the ways in which Japanese and English are read, the American volumes published by Vertical Inc. are presented as mirror images of Tezuka's original work so they can be read from left to right, rather than from right to left. Nearly three decades after the manga was completed, an anime film adaptation was released in 2011. A second film was released in 2014.
