Cobb Divinity School (also known as Bates Theological Seminary or the Free Will Baptist Bible School), founded in 1840, was a Free Will Baptistgraduate school affiliated with several Free Baptist institutions throughout its history. Cobb was part of Bates College in Lewiston, Maine, United States from 1870 until 1908 when it merged with the college's Religion Department.

The school and its library were removed to Lewiston in 1870 and became a graduate school (known as Bates Theological Seminary until 1888) of Bates College. In 1888, it was renamed Cobb Divinity School in honor of J.L.H Cobb, a prominent businessman at the Bates Mill in Lewiston who had donated $25,000 to the Divinity School at Bates. In 1891, President of Bates College Oren B. Cheney amended the school's charter requiring that Bates' president and a majority of the trustees be Free Will Baptists. Following Cheney's retirement, the amendment was revoked in 1907 at the request of his successor, President George C. Chase, and the board of trustees. In 1907, the Maine Legislature amended the college's charter removing the requirement for the president and majority of the trustees to be Free Will Baptists, thereby allowing the school to qualify for Carnegie Foundation funding of professor's pensions. Cobb Divinity School was disbanded in 1908, with much of its curricula and faculty becoming the Bates College Religion Department. In 1911, the Northern Free Will Baptist Conference merged with the Northern Baptist Conference, now known as the American Baptist Churches USA. Bates remained nominally affiliated with the Baptist tradition until 1970 when the college catalogue no longer described the school as a "Christian college".
