Jeremiah Morrow (October 6, 1771 – March 22, 1852) was a Democratic-Republican Party politician from Ohio. He served as the 9th Governor of Ohio, and the last Democratic-Republican to do so.
Morrow was born near Gettysburg, Pennsylvania, to the descendants of Scots-Irish immigrants. He moved to the Northwest Territory in 1795.
After serving in the Territorial House of Representatives and Territorial Senate, as well as a delegate to the 1802 Constitutional Convention, he was elected to the first State Senate a year later and served six months before becoming Ohio's first member of the United States House of Representatives. Morrow won four additional full terms. He ran for the U.S. Senate in 1812 and served a single term from 1813-1819, and did not seek re-election. He won election to the governorship in 1822 and served for two two-year terms. He declined to serve a third term, instead returning to the Ohio House of Representatives and State Senate. Morrow was sent back to Washington again in 1841, and served two more years in the House, but refused to be renominated in 1842, believing himself too old.
He is the namesake of the highest bridge in Ohio, of Morrow County, and of Morrow, Ohio.
