Sir Nicholas Woodroffe (Woodruff, Woodrofe, etc.) (c. 1530–1598) was a London merchant of the Worshipful Company of Haberdashers, who, through the English Reformation, rose in the Alderman class to become a Master Haberdasher, Lord Mayor of London and Member of Parliament for London. Through the complexities of his family's relationships, and the position and security which they afforded, he lived to establish his family among the armigerous houses of late Elizabethan Surrey.
