Seneca Caverns is a karst show cave in Germany Valley near Riverton, West Virginia, USA.

A German-American settler named Phillip Dieter (later Teter; 1740-1813) purchased the land surrounding Seneca Caverns in the 1770s.

[1] He may have first entered the cave on a quest for water to supply his livestock.

The Teter family maintained ownership until 1928, at which point it became property of the Harman family, who began the process of commercializing the cave.

In 1930 the new owners opened it to the public as a show cave.
