(June 13, 1803—September 25, 1868) was an American prelate of the Roman Catholic Church who served as the first bishop of the Diocese of Covington, Kentucky from 1853 until his death in 1868.

His grandfather, Timothy Carrell, was a native of Ireland and came to the United States before the Revolutionary War, establishing himself as a grocer on Water Street in Philadelphia.

The seventh of eight children, he was born and raised in the former mansion of William Penn, at the corner of Market Street and Letitia Court.

He did not lose sight of his chosen vocation, and soon afterward entered the Theological Seminary of St. Mary's in Baltimore.

Having completed his studies, Carrell was ordained to the priesthood in December 1827, at St. Augustine's Church in Philadelphia by Bishop Henry Conwell.

In all these positions he proved himself a laborious priest and a good pastor, winning for himself not only the high esteem and friendship of Bishop Francis Patrick Kenrick, but also the kind regard of the entire population, including great numbers of other denominations, especially of the Religious Society of Friends at Philadelphia.

Churches and schools began to spring up in various parts of his diocese, and strides were rapidly made by religion and education during his administration.

The news of battle, carnage, and death during the Civil War deeply affected him, and he invariably requested his friends to spare him the pain of listening to them.
