Marion Park, public park in Capitol Hill, Washington, D.C., United States

Marion Park is a public park in the Capitol Hill neighborhood of Washington, D.C., bounded by 4th Street, 6th Street, and E Street Southeast. Its open lawns mix green grass with patches of bare tan dirt, shaded by large leafy trees, and a dark paved path curves across the middle ground near a low white building on one side.

The land was known as Houp's Addition in 1764, owned by Jonathan Slater, before being sold to William Prout and turned over to the federal government in 1791. By 1886, improvements gave the park an ornamental look, and in 1887 it was first called Marion Park after the Revolutionary War leader Francis Marion.

Locally, people call it Turtle Park because of the large concrete turtle in the playground. Dog owners gather on the grass while toddlers play nearby, and the layout still hints at the old carriage paths that once shaped how visitors moved through the space.

The park is easy to reach on foot from nearby streets, with wide brick walkways and open lawns that make it simple to move around. Benches and shaded spots under mature trees give visitors a convenient place to rest, and the level ground suits strollers and wheelchairs.

A large Hilton Iron Vase once stood in the center, filled with tropical flowers every summer and used to direct carriage traffic. The vase was removed in 1963, and traffic was shifted outside the park, leaving no trace of that old circular route.
