The Linsly School, formerly known as the Linsly Military Institute, is a boarding and day school located in Wheeling, West Virginia. It was founded in 1814 by Noah Linsly and chartered by the State of Virginia in the same year. The school is the oldest preparatory school west of the Alleghenies. It was originally known as the Lancastrian Academy. In 1861, the school adopted the dress and discipline of an all-boys military school. In 1978 the board of trustees voted to change the military structure and adopt the philosophy of a traditional boys preparatory school.
