St. Thomas Aquinas High School was a Roman Catholic senior high school in New Britain, Connecticut. In 1995 the school established a board, Aquinas Foundation, which implemented fundraisers. Circa 1995 the school had 240 students. The enrollment declined further, and as of 1999 the fundraisers had not resulted in a lot of money going to the school. In the summer of 1999 there were fewer than 100 enrolled students for the upcoming school year, including only 11 9th grade (freshmen) students. In July 1999 the school announced it was closing as the enrollment was too low.
