Thomas Parker Sanborn (; February 24, 1865 - March 2, 1889) was an American poet.
The eldest son of abolitionist, social scientist, and memorialist of American transcendentalism Franklin Benjamin Sanborn, Thomas became a close friend of philosopher George Santayana and was a food model for the protagonist in Santayana's only novel, The Last Puritan.
With five college friends, Thomas founded The Harvard Monthly.
