Marietta College (Latin: Collegium Mariettensis) is a co-educational liberal arts private college in historic Marietta, Ohio, USA, (population 14,000+) which was the first permanent settlement of the Northwest Territory. Historically preceded by the community's Muskingum Academy, established in 1797, today's College was chartered in 1835 and the first president was the Rev. Joel H. Linsley. In 1860, Marietta became the sixteenth college awarded a chapter of Phi Beta Kappa, the world's oldest honorary society.
