Erasmus Hall High School was a four-year public high school located at 899-925 Flatbush Avenue between Church and Snyder Avenues in the Flatbush neighborhood of the New York City borough of Brooklyn. It was founded in 1786 as Erasmus Hall Academy, a private institution of higher learning named for the scholar Desiderius Erasmus, known as Erasmus of Rotterdam, a Dutch Renaissance humanist and Catholic Christian theologian. The school was the first secondary school chartered by the New York State Regents. The clapboard-sided, Georgian-Federal-style building, constructed on land donated by the Flatbush Reformed Dutch Church, was turned over to the public school system in 1896.
