Fox Hollow is a tributary of Mehoopany Creek in Wyoming County, Pennsylvania, in the United States.

Fox Hollow begins to the south of Little Round Top in a large wetland that extends into Windham Township.

It flows east for several hundred feet before turning southeast for a few tenths of a mile, entering a valley.

[5] The Fox Hollow Swamp in Windham Township is listed on the A Natural Areas Inventory of Wyoming County.

It is a northern broadleaf conifer swamp in a location without many large wetlands and has the potential to serve as a habitat for rare species, though none were observed when the Inventory was compiled.

The swamp has an area of 40 to 50 acres (16 to 20 ha) and originally consisted mainly of black ash, hemlock, and yellow birch.
