Ross School is a private school K-12 school located on 63 acres in the Town of East Hampton, on Long Island, New York, United States. Named after her late husband Steven J. Ross, the school was founded in 1991 by Courtney Sale Ross as a girls-only day school for their daughter Nicole and several of her friends. The original pre-nursery, nursery, and pre-kindergarten programs were discontinued in September 2020. Ross School transitioned to a co-ed boarding school in 2002 after its founder discontinued private funding. Students in grades 6-12 may board five days per week or full-time. The school has supplemented its budget by catering breakfast and lunch from its café to the Bridgehampton School and offering culinary arts and landscaping classes to East Hampton High School students.
