The Bordentown Military Institute was a private high school in Bordentown, New Jersey, United States, from 1881 to 1973.
The institute was created in 1881, when Reverend William Bowen purchased the Spring Villa Female Seminary building and reopened it as the Bordentown Military Institute. In 1972, it was merged with the Lenox School in Lenox, Massachusetts. The combined entity was shut down the following year as the Vietnam War reduced the popularity of a military education.
