Mary Moser RA (27 October 1744 – 2 May 1819) was an English painter and one of the most celebrated female artists of 18th-century Britain.

One of only two female founding members of the Royal Academy in 1768 (along with Angelica Kauffman), Moser painted portraits but is particularly noted for her depictions of flowers.

Ten years later, however, her thirst for professional recognition led her to join with 35 other artists (including her father) in forming the Royal Academy, and, with Angelica Kauffman, she took an active role in proceedings.

In the 1790s, Moser received a prestigious commission, for which she was paid over £900, from Queen Charlotte to complete a floral decorative scheme for a room in Frogmore House in Windsor, Berkshire.

"One of the most celebrated women artists of 18th-century Britain,"[9] Moser died in Upper Thornhaugh Street, London, on 2 May 1819, and was buried, alongside her husband in Kensington Cemetery.
