The 1888 Republican National Convention was a presidential nominating convention held at the Auditorium Building in Chicago, Illinois, on June 19–25, 1888. It resulted in the nomination of former Senator Benjamin Harrison of Indiana for president and Levi P. Morton of New York, a former Representative and Minister to France, for vice president. During the convention, Frederick Douglass was invited to speak and became the first African-American to have his name put forward for a presidential nomination in a major party's roll call vote; he received one vote from Kentucky on the fourth ballot.
The ticket won in the election of 1888, defeating President Grover Cleveland and former Senator Allen G. Thurman from Ohio.
