Mary Artemisia Lathbury (August 10, 1841 - October 20, 1913) was an American poet and hymnwriter.

She was originally an artist and also taught art in Vermont and New York schools, but later transitioned more towards religious work and writing.

Lathbury said that she became involved with Christian service full-time because God said to her, "Remember, my child, that you have a gift of weaving fancies into verse and a gift with the pencil of producing visions that come to your heart; consecrate these to Me as thoroughly as you do your inmost spirit".

Her hymns include Day is Dying in the West and Break Thou the Bread of Life.

[2] Lathbury died on October 20, 1913, in East Orange, New Jersey, and was buried at Rosedale Cemetery in the same city.
