Emerson Preparatory School (also known as Emerson) was a small private high school in Northwest Washington, D.C., founded in 1852 as the Emerson Institute. It was Washington's oldest co-ed college preparatory school. The school closed at the end of the 2020-21 school year.
The school was located inside the Clocktower Building in Dupont Circle. Emerson had occupied that location since 2019, after moving from a temporary location in the Twelfth Street YMCA Building. Before 2017, Emerson spent eighty years in their own building across from the American Enterprise Institute. Most students used WMATA to get to and from school.
Emerson Preparatory School was a member of the Association of Independent Maryland and DC Schools (AIMS).
