Charles B. Farwell (July 1, 1823-September 23, 1903) was a U.S. Congressman and Senator from Illinois.
Farwell was born in Painted Post, New York and attended Elmira Academy before moving to Illinois in 1838. He first tried his hand at surveying and farming before moving to Chicago in 1844, when he went into banking. From 1853-1861, he served as the Clerk of Cook County. He served in the U.S. House of Representatives from 1871 to 1875. He declined to run again, but in 1881, he was elected for another term. Upon the death of John A. Logan in 1887, Farwell was elected to serve out Logan's term in the U.S. Senate, but refused to run for re-election to a full term.
