Shusaku Endo (?? ??, Endo Shusaku, March 27, 1923 – September 29, 1996) was a Japanese author who wrote from the rare perspective of a Japanese Roman Catholic.
Together with Junnosuke Yoshiyuki, Shotaro Yasuoka, Junzo Shono, Hiroyuki Agawa, Ayako Sono (also Catholic), and Shumon Miura, Endo is categorized as part of the "Third Generation" (that is, the third major group of Japanese writers who appeared after World War II).
The 2016 film Silence, directed by Martin Scorsese, is an adaptation of Endo's 1966 historical novel of the same name.
