Wilmington Friends School is a private Pre-kindergarten-12 school in unincorporated New Castle County, Delaware, United States, near Wilmington. It is affiliated with the Society of Friends, also known as the Quakers.
The school was founded in 1748 by members of the Wilmington Monthly Meeting of Friends.
Of the school, Delaware historian Benjamin Ferris wrote in the 19th century, "Thousands of children have there received the first rudiments of an English education."
In 1937, the Friends School moved from its original site to its current location in Alapocas, just outside the city of Wilmington. In 2019, it was announced that the school was consolidating all grades into one building and selling its lower grade school building, which had housed grades pre-K to fifth grade. The building and about 20 acres of property was sold to the pharmaceutical research company Incyte.
