Leonardo Kimura, SJ (also known as レオナルド 木村 or レ゜オナルド, 1575 – 18 November 1619) was a Japanese Catholic evangelist and teacher.

Killed as a victim of anti-Catholic persecution in Japan, he was beatified by Pope Pius IX in 1867.

[6] After a period of increased missionary activity by the Catholic Church, it is estimated that 400,000 people professed this religion in Japan in 1613.

[3] That year, the Shogun Tokugawa Hidetada issued a decree under which, under the threat of losing their lives, all missionaries were to leave the country, and the practice and teaching of the religion were forbidden.
