The Grey Stone of Trough is an historic boundary marker in Bowland Forest High, in the Trough of Bowland, Lancashire, England. A Grade II listed structure, erected in 1897 and standing on Trough Road, it marks the line of the pre-1974 county boundary between Lancashire and the West Riding of Yorkshire.
