Eagle Rock is a census-designated place (CDP) in Botetourt County, Virginia, United States, located along the James River between Iron Gate and Buchanan. It was first listed as a CDP in the 2020 census with a population of 209.

Eagle Rock had the last lock of the James River and Kanawha Canal.

This was the location of the kilns for making lime. Limestone was transported across the James River via a tram system and then burned in the kilns to make lime. Originally a river ford, known as "The Free Stone Ford", allowed mule drawn wagons to cross. In May 1884 a bridge was constructed across the river for the limestone. Later, large towers were constructed and the lime sent across the river by cable. Old quarries and locally known Quarry Hill are located on either side of US 220. The Bessemer Archaeological Site, Phoenix Bridge, and Roaring Run Furnace are listed on the National Register of Historic Places.

At the end of the James River and Kanawha Canal system, transportation was done by rail. Eagle Rock was the point of convergence of the Richmond and Alleghany Railroad (soon to be known as the Chesapeake and Ohio Railway, and later CSX Transportation) and the Craig Valley Line, which ran to Surber Station and on to New Castle, Virginia.

Eagle Rock is located at 37°38′26″N 79°48′04″W / 37.64056°N 79.80111°W / 37.64056; -79.80111 (37.6422510, −079.7918942).

According to the United States Census Bureau, the CDP has a total area of 0.71 square miles.
