Yasuzo Shimizu (清水 安三 Shimizu Yasuzō?, June 1, 1891 – January 17, 1988) was a Japanese educator and Christian missionary in China. He established the Chongzhen School for the poor in Beijing, and the Obirin University in Tokyo.
Yasuzo Shimizu was born in Shiga Prefecture, Japan, and became a Christian under the influence of William Merrell Vories, who was in Shiga as an architect and a lay missionary. He graduated from the Theological School of Doshisha University, Kyoto, in 1916, and went to China as a missionary in the following year, first to Dalian, then to Tianjin, and finally to Beijing where he and his wife, Miho (Japanese: 美穂), founded a girls' school for the poor.
In 1924, Shimizu was ordained as a minister in Osaka, and went to U.S. to study at Oberlin College, Ohio, with a financial help provided by Magosaburō Ōhara of Kuraray. Upon his return to China, as Miho died of disease, he married Ikuko Koizumi (Japanese: 小泉郁子), and they together expanded the school for the poor, which was later in 1936 renamed as the Chongzhen Middle School (Chinese: 崇貞中學). They also founded the Ailin Hall (Chinese: 愛鄰館), an almshouse.
