Mary Augusta McEvoy née Spencer Edwards (22 October 1870 – 4 November 1941) was a British artist known for her paintings of portraits, interiors and flowers.

[3][6] In 1902 she married the artist Ambrose McEvoy and in due course gave up a full-time art career although she worked with her husband on at least one major project.

In 1909 Ambrose McEvoy was commissioned to paint a series of decorations for St Columba's Church, Long Tower in Derry which were to consist of three original works and twenty-two copies of bible scenes as depicted by Old Masters.

[7] While Ambrose created the three original pieces, it is believed that Mary worked on the twenty-two copies, finding suitable sources, making cartoons and then painting enlarged versions onto copper panels for the church.

[7][4] The Tate collection holds her 1901 painting Interior: Girl Reading and also a bust of her by the sculptor Jacob Epstein.
