Charles Tuohy (1754–1828) was an Irish Roman Catholic prelate who served as the Bishop of Limerick from 1813 to 1828.

He was ordained in Paris in 1780, and he continued his studies, receiving a Doctorate in Divinity in 1784.

He returned to Limerick that year and was appointed a curate in St. John's Parish.

This was an important period of transition in Irish civil and ecclesiastical history between the Acts of Union 1800 and Catholic emancipation.

Tuohy was a tireless worker for the rights of the church and his Catholic flock.
