Crucible is a census-designated place and coal town in Greene County, Pennsylvania, United States.

Some sources cite that the mine opened in 1910, but others claim that the official opening was in 1913 after the sale of 2,000 acres (810 ha) to Crucible Coal, Co.[5] Crucible had many features typical of a coal town, including company housing, a company store, and a post office.

[7] The school has subsequently been shut down, but had been used as a haunted house for fundraisers and as a training facility for the local volunteer fire department; it has been demolished.

Crucible is located in northeastern Greene County, in the northern part of Cumberland Township, on the south side of the Monongahela River.

The CDP begins at the riverbank and extends south up the 200-foot-high (60 m) river bluff to a plateau where most of the houses are located.
