Martha Julia Cartmell (December 14, 1845; March 20, 1945) was a Canadian Methodist/United Church missionary and educator in Japan.
The daughter of James Cartmell, a stone cutter, and his wife Sarah, she was born in Thorold[1] and was educated in Hamilton and Toronto.
Cartmell became a missionary and left San Francisco for Japan in 1882 and established a Christian school for girls, Toyo Eiwa Jogakuin, two years later[1] in Roppongi.
She recovered in Canada, working at the General Mission in Victoria, British Columbia from 1890 to 1892, and returned to Tokyo.
In 2013, the alumni association for the Toyo Eiwa school donated cherry trees in her honour to Hamilton and to Thorold.
