John Carroll, American archbishop, founder of Georgetown University (d. 1815)
John Carroll (January 8, 1735 – December 3, 1815) was an American prelate of the Roman Catholic Church who served as the first bishop and archbishop in the United States. He served as the ordinary of the first diocese and later Archdiocese of Baltimore, in Maryland, which at first encompassed all of the United States and later after division as the eastern half of the new nation.

Carroll is also known as the founder of Georgetown University (the oldest Catholic college / university in the United States), and of St. John the Evangelist Parish of Rock Creek (now Forest Glen), the first secular (or diocesan, meaning that its clergy did not come from monastic orders) parish in the country.
