Eaglebrook School is an independent junior boarding and day school for boys in grades six through nine. It is located in Deerfield, Massachusetts, on the Pocumtuck Range near Deerfield Academy and sited on an 724-acre (2.93 km2) campus which is also preserved by the Deerfield Wildlife Trust. Eaglebrook School is accredited by the Association of Independent Schools in New England (AISNE).

Eaglebrook has a student body of approximately 250 boys in grades six, seven, eight, and nine (forms 3 through 6). Girls may only attend if their parents work or live on campus. Eaglebrook has its own alpine ski area (the Easton Ski Area), indoor 25-yard six-lane swimming pool, and a state-of-the-art hockey rink arena indoors. Whipple Pond, located in the center of campus, is stocked with trout and bass for fishing in the spring and fall. In the winter the pond serves as the water source for snowmaking. The Chase Learning Center, at the heart of campus, includes classrooms and a multi-purpose assembly area which is called the "Pit". Although it was once the meeting place for the school's theater program, it is now currently just being used as an assembly area because the theater program has fallen apart. There are three other classroom buildings for science, language, and arts, including digital photography, woodworking shops, stained glass, stone carving, black and white photography, and many more.

Part of Eaglebrook School's mission is "to help each boy come in to full and confident possession of his innate talents, to improve the skills needed for the challenges of secondary school, and to establish values that will allow him to be a person who respects individual differences and acts with thoughtfulness and humanity."
