Cornelia Arnolda Johanna "Corrie" ten Boom (15 April 1892 – 15 April 1983) was a Dutch watchmaker and later a Christian writer and public speaker, who worked with her father, Casper ten Boom, her sister Betsie ten Boom and other family members to help many Jewish people escape from the Nazis during the Holocaust in World War II by hiding them in her home. They were caught, and she was arrested and sent to the Ravensbrück concentration camp.

She trained to be a watchmaker herself, and in 1922, she became the first woman to be licensed as a watchmaker in the Netherlands. Over the next decade, in addition to working in her father's shop, she established a youth club for teenage girls, which provided religious instruction and classes in the performing arts, sewing, and handicrafts.
