Thomas Bennett (October 15, 1788 – February 12, 1872) was a magistrate and political figure in Newfoundland. Born in Shaftesbury, Dorsetshire, England, Bennett first worked for the British government in the Commissariat Department and moved to St. John's, Newfoundland, in the early 1820s to work in his brother Charles' mercantile business. Both brothers became important members of the business community and his brother later served as Premier of Newfoundland. In 1828, Bennett married Hannah Hutchings.
