Name and origin

The name is often shortened to "Mt Joy", as in Mencken. However, citizens of the town often point out that this abbreviation is not proper because the town is not named for a mountain but is named after the "Good Ship" Mountjoy which famously broke a Catholic siege during the Siege of Derry. Due to the early settlement of the Protestant Scots-Irish in this region of Pennsylvania, many of the municipalities in the area were given names common to the North of Ireland, such as Derry Township, Londonderry Township, South Londonderry Township, Mount Joy Township, East Donegal Township, West Donegal Township, and Rapho Township.
Mount Joy is often named in lists of "delightfully-named towns" in Pennsylvania Dutch Country, along with Intercourse, Blue Ball, Lititz, Bareville, Bird-in-Hand and Paradise.
