Alonzo Hartwell (19 February 1805 in Littleton, Massachusetts – 17 January 1873 in Waltham, Massachusetts) was an engraver and portrait artist in Boston, Massachusetts, in the 19th century. He trained with Abel Bowen in Boston and in 1826 went into business for himself. Hartwell's work appeared in the American Magazine of Useful and Entertaining Knowledge and other publications. Among Hartwell's students were artists George Loring Brown and Benjamin F. Childs. In 1850, he received the silver medal of the Charlestown, Massachusetts, Mechanics' Association. He continued as an engraver until 1851, when he turned to portrait painting. One of Hartwell's children, Henry Walker Hartwell, became an architect in the Boston firm Hartwell and Richardson.
