The Colonial Dames of America is an American organization composed of women who are descended from an ancestor who lived in British-America from 1607–1775, and was of service to the colonies by either holding public office, being in the military, or serving the Colonies in some other "eligible" way.
The National Headquarters is presently at Mount Vernon Hotel Museum in New York, which was purchased by the CDA in 1924.
The organization was founded in 1890, shortly before the founding of two similar societies, The National Society of the Colonial Dames of America and the Daughters of the American Revolution.
