Stanley Griswold (November 14, 1763 - August 21, 1815) was a Democratic-Republican politician from Ohio. He served in the U.S. Senate.

Born in Torrington, Connecticut, Griswold served in the militia during the Revolutionary War. After graduating from Yale College in 1786, he worked as a newspaper editor and pastor. After serving in the territorial government of Michigan from 1805-1808, Griswold moved to Ohio, and was appointed to the Senate to fill the vacancy created by the resignation of Edward Tiffin, serving from May 18, 1809 until a special election was held to choose a successor on December 11, 1809. Griswold then moved to the Illinois Territory, where he was appointed as a federal judge, serving on the bench and as a lawyer until his death.
