The Deer Park Union Free School District is a school district headquartered in and serving nearly the entirety of Deer Park in the Town of Babylon in Suffolk County on Long Island in New York.
There have been schools in Deer Park for many years, the was a one room schoolhouse in the area since at the latest 1872. In 1967, several Wyandanch parents campaigned for the dissolving of the Wyandanch School District of the time (with the support of the NAACP) to the Third Supervisory District principal of the region, and for the students to be sent to nearby districts, including Deer Park. It was then proposed to State Education Commissioner Dr. James Allen. Allen later rejected it in 1968, "serious obstacles imposed by existing law". Robert Frost Middle School was opened in 1967, as Deer Park Junior High School. A showcase dedicated to the history of Deer Park is featured in the main lobby of Deer Park High School, showing the history of Deer Park, including memorabilia such as trophies and photos from as early as 1964.
