Ellen Clementine Howarth (born Ellen Clementine Doran in Cooperstown, New York, May 17, 1827, died Trenton, New Jersey, December 23, 1899), was an American poet.
The daughter of a calico printer, and employed as a factory worker at the age of seven, she married Joseph Howarth, in the same occupation.
She lived at Trenton, New Jersey in extremely reduced circumstances until friends secured her a comfortable subsistence.
Howarth said her poems came to her as she did housework, and she only wrote them down when she considered them finished.
They were initially published in newspapers in Trenton under the pen name "Clementine", and then in magazines; Richard Gilder helped her find markets for them.
