Nathan Williams (December 19, 1773 – September 25, 1835) was a United States representative from New York and the first lawyer to permanently establish a law practice in Utica.

After his parents property was "lost in the vicissitudes of the revolution"[1] He moved with them to Troy, New York in 1786, studied law, was admitted to the bar in 1795, and commenced practice in Utica.

He soon established a large law practice, however, rather than resorting to lawsuits he would instead often work with his clients in an effort to aid them and settle out of court.

He was at one period counsel for the Oneida Indians, and the epithet they gave him does honor to the man, while revealing the justice of their discrimination; in their tongue he was the " Upright Friend.
