Atlantic Union College (AUC) was a Seventh-day Adventist college in South Lancaster, Massachusetts. It was absorbed by Washington Adventist University in 2011 after losing accreditation from the New England Association of Schools and Colleges. In 1882, the school was organized as a preparatory school under Stephen Nelson Haskell to serve the needs of Adventist constituents in the northeastern part of the United States and Bermuda, and was named "That New England School". The next year, it was incorporated and renamed South Lancaster Academy. In 1918, it was once again renamed Lancaster Junior College. Then, in 1922, it was yet once again renamed Atlantic Union College after being authorized to grant degrees in the state of Massachusetts. That year, the academy and college separated. In 1933, Governor Joseph Ely granted AUC the right to confer the bachelor of arts degree. In 1945, the school was first accredited by the New England Association of Schools and Colleges (NEASC). In 1954, it was authorized to grant the bachelor of science degree. Herbert E. Douglass was president from 1967 to 1970. In 1990, Atlantic Union was authorized to grant the master of education degree.
