Carroll, Charles (1737–1832), an American Revolutionary patriot and statesman. He was the wealthiest signer of the Declaration of Independence and the only Roman Catholic. Living to be 95, he was the last signer to die.

Carroll was born in Annapolis, Maryland, and was educated in France and England. Upon his return, he became involved in his father's businesses. To distinguish himself from his father and similarly named cousins, he called himself “Charles Carroll of Carrollton,” the Carrollton referring to a large parcel of land his father gave him.

In 1776 Carroll and his cousin John Carroll were members of a commission sent to Canada to seek to persuade the Canadians to join the revolutionary cause. He served in the Continental Congress in 1776 and during 1777–78. He was a United States senator from Maryland, 1789–92.
