River Hill is the last[1] and westernmost village to be developed in the town of Columbia, Maryland, United States, though some residents maintain addresses in Clarksville.

The area was used as a game preserve by James Rouse to entertain clients and personal hunting during the buildout of the Columbia project.

[1] The original plan called for the village to be connected to the rest of Columbia via an extension of Little Patuxent Parkway.

In addition, a dam on the Middle Patuxent River would have created a large lake in that watershed.

The original plan called for 90 acres (360,000 m2) to be devoted to apartments, but the rural neighbors wanted a lower population density.
