Vichna Kaplan (1913 – August 20, 1986) was an Orthodox Jewish teacher and school dean who, together with her husband Rabbi Boruch Kaplan, brought the Bais Yaakov movement to America. A prize pupil of Sarah Schenirer, the founder of Bais Yaakov in Poland, Kaplan opened the first Bais Yaakov High School in Williamsburg, New York, in 1938. She later opened the first Bais Yaakov Teachers Seminary, which provided teachers for all Bais Yaakov schools that subsequently opened in America and Israel.
