Civilla Durfee Martin (August 21, 1866 – March 9, 1948) was a Canadian-American writer of many religious hymns and gospel songs in the late 19th century and early 20th century. Her husband, Walter Stillman Martin (1862–1935), studied ministry at Harvard University, where he became a Baptist minister but later switched to the Disciples of Christ. Together they created hymns and songs which have become widely known. Some of her most popular pieces include "God Will Take Care of You", "One of God's Days", "Going Home", "The Old Fashioned Way", and "His Eye Is on the Sparrow".
