Henry Havelock Ellis (2 February 1859 - 8 July 1939) was a British sexologist, physician, and social reformer.

== Ellis, son of Edward Peppen Ellis and Susannah Mary Wheatley, was born in Croydon, then a small town south of London. His father was a sea captain, his mother the daughter of a sea captain, and many other relatives lived on or near the sea. At seven years of age, his father took him on one of his voyages, during which he called at Sydney, Callao and Antwerp. After his return, Ellis went to a fairly good school, the French and German College near Wimbledon, and afterward attended a school in Mitcham.
