Park Hall is an unincorporated community in Washington County, Maryland, United States.

Park Hall is a geographical place name for a largely undeveloped rural area on the western slope of South Mountain in southeastern Washington county Maryland.

Originating in 1731, it was the name chosen by owner William Parks for the very first land tract awarded by the colonial government of Maryland in the region west of South Mountain.

[2] The property surveyed for 1,550 acres stretched along the lower west slope encompassing what was an early trail into the region.

All three routes over the mountain would remain important though, as evidenced by the battle's fought to control these three gaps in September 1862.
