The Rockwell Formation is a late Devonian and early Mississippian mapped bedrock unit in West Virginia, Maryland, and Pennsylvania, in the United States.

The Rockwell Formation was described at its type section at Rockwell Run in West Virginia as soft arkosic sandstone, fine hard conglomerate, and buff hackly shale.

[3] It was first described in Maryland by H. E. Vokes (1957),[4] and later described in central Pennsylvania by C. R. Wood (1980).

[1] It has been reduced in rank to a member of the Price Formation in West Virginia.

Lessing, Dean, and Kulander (1992) mapped the Meadow Branch synclinorium in Berkeley County, West Virginia, and noted that the Rockwell is approximately 200 meters thick here and that a 2-meter thick diamictite is present near the base.
