Amy Clarke (pen name, Mrs. Henry Clarke; 17 April 1853 – 4 March 1908), was an English writer of historical fiction and children's books.

The daughter of Joseph Henry Key and Elizabeth Hosking, Clarke was born Amy Key in Plymouth in 1853.^[1] She started writing when young, publishing a story in the magazine Good Words when she was 16. At 20, she obtained a first in the Cambridge Examination and began teaching at Plymouth High School for Girls. Two years later she took a year's leave to read mathematics at Newnham College, Cambridge. She left Plymouth High School in 1880 to become the first headmistress of Truro High School for Girls.

Clarke still continued her education, attending London University to earn an external MA. While at university, she met the lecturer Henry Clarke, whom she married in 1889. They had four children: John Henry Clarke (born 1891), Walter Oakley Clarke (1892), Amy Key Clarke (1893–1980) and Wilfrid Kinton Clarke (1894).^[2] After her marriage, Clarke limited her teaching to occasional lectures at Westfield College. Her main occupation became writing.

In 1908, she died of cancer.
