Ellmont is a ghost town site near Brockway, in the Elk County−Jefferson County areas of western Pennsylvania.
It is located along a present-day bicycle and hiking rail trail, built on the old railroad right of way along Little Toby Creek in Jefferson and Elk Counties.
A steel mill was built nearby in 1883, leading to the establishment of the town of Blue Rock, later renamed Ellmont.
After the mill burned down, the town was abandoned.
