Mary Ann Croswell (died 1830) was an English silversmith. Croswell was the widow of smallworker Henry Croswell I, and registered her first mark on 21 May 1805 and a second on 29 August 1816. A small worker - like her husband - she gave an address of 31 Monkwell Street in London. In October 1819, her son, Henry Croswell, became her apprentice. She may have been active as late as 1830; her will, in which the business was left to her son, was proved on 29 January that year. Other apprentices besides her son included Joseph Price and John Goodluck. A George III toy rattle of silver and coral, dating to 1808 and attributed to Croswell, is in the collection of the National Museum of Women in the Arts.
