The Beck-Warren House, also known just as the Warren House, is an historic house on 1 Prescott Street in Cambridge, Massachusetts. Now on the campus of Harvard University, this large Greek Revival wood frame house was built in 1833 for Professor Charles Beck. The house was purchased by Henry Clarke Warren, a Sanskrit scholar, in 1891, and by Harvard in 1899. When first acquired by the university, it was used to house the philosophy library, and then the English department. It was moved in 1900 (within its historic lot) to make room for the construction of the Harvard Union. Since 1997, it has served as offices for other Harvard organizations.
