Christopher G. Champlin (April 12, 1768 - March 18, 1840) was a United States Representative and Senator from Rhode Island. Born in Newport, he completed preparatory studies, was graduated from Harvard College in 1786, and continued his studies at the College of St. Omer in France. Champlin was elected as a Federalist to the Fifth and Sixth Congresses (March 4, 1797-March 3, 1801). He engaged in mercantile pursuits, and was later elected to the U.S. Senate to fill the vacancy caused by the death of Francis Malbone and served from June 26, 1809, to October 2, 1811, when he resigned. He was president of the Rhode Island Bank until a short time before his death in Newport in 1840; interment was in Common Burial Ground.
