Susanna Highmore was an English poet with a relatively small literary output. She was the wife of Joseph Highmore, whom she married on 28 May 1716. She was listed as "an heiress", while Joseph Highmore was a portrait painter in high demand, and the couple lived in London and associated with Isaac Watts, William Duncombe, and Samuel Richardson. They had two children, Anthony Highmore and Susanna.
