Cottage City, officially the Town of Cottage City, is a town in Prince George's County, Maryland, United States. Per the 2020 census, the population was 1,335. Cottage City is a small, quiet community lying between Eastern Avenue (the border with Washington), Brentwood, Colmar Manor, and the Anacostia River. Cottage City was developed, beginning in 1870, under the name of "The Highlands". The area was incorporated in 1924 as Cottage City.
Its history dates to pre-revolutionary America; old records indicate that the area was home to several of the Potomac River Indian tribes. With the coming of European settlers, the area became noted for its deep-water Anacostia River port, known then as Harrison's Landing. Contributing to the economy of Harrison's Landing was Moyer's Grist Mill located in Yarrow, the very first mill of its type between Baltimore and Alexandria, Virginia. Yarrow was renamed several times, but today we know Yarrow as Cottage City.
