The 1823 Massachusetts gubernatorial election was held on April 7.
Federalist Governor John Brooks did not run for a seventh term in office. William Eustis, a Republican, was elected to succeed him over U.S. Senator Harrison Gray Otis. Eustis was the first Republican elected Governor since Elbridge Gerry in 1811; no Federalist would ever win a gubernatorial election again, and the state party rapidly collapsed.
