Northeastern Seminary (NES) is a graduate school of theology located on the campus of Roberts Wesleyan College.

It is also accredited by the Middle States Association of Colleges and Schools and the New York State Board of Regents University of the State of New York.

Roberts Wesleyan College was originally established as Chili Seminary by Benjamin Titus Roberts in 1866. Roberts was a social activist who opposed slavery and oppression of the poor, and was a supporter of women's right to vote. He began the school to train young people to become servant leaders with high moral character.

In 1885, its name changed to Chesbrough Seminary in response to the $30,000 gift of benefactor A.M. Chesbrough. In 1945, it was renamed Roberts Junior College in honor of B.T. Roberts, the founder both the college and of the Free Methodist Church. Four years later, it was renamed as Roberts Wesleyan College in order to pay homage to John Wesley, the founder of Methodism and the Wesleyan Church.

In 1998, Roberts Wesleyan College established Northeastern Seminary as its graduate school of theology.
