Joseph Grafton (June 9, 1757 – December 16, 1836)[1] was an American minister, a founder of the Newton Theological Institution.

[2] For more than forty-eight years he was pastor of the First Baptist Church in Newton, Massachusetts.

As the minister of a member church of the (Baptist) Warren Association, Grafton served on committees to advise individuals and churches who were taxed in order to pay the town-supported Congregational minister's salary.

[3] In September 1793, members of the Warren Association elected Joseph Grafton as one of twelve founding Trustees of the Baptist Education Fund.

Grafton's biography, written by Samuel Francis Smith, was published in Boston in 1849.
