Mount Joy, PA
Mount Joy is a borough in Lancaster County, Pennsylvania, United States. The population was 6,765 at the 2000 census.
Mount Joy is often named in lists of "delightfully-named towns" in Pennsylvania Dutchland, along with Intercourse, Blue Ball, Lititz, Bareville, Bird-in-Hand and Paradise.
The name is often shortened to Mt Joy, as in Mencken (1963), but this is incorrect, since the "mount" in Mount Joy does not refer to a mountain. The town's name is actually derived from an English surname, Mountjoy and was brought to the colonies, along with the name Donegal (name of the school district in Mount Joy) by settlers from Ireland.
