The 1900 Republican National Convention was held June 19 to June 21 in the Exposition Auditorium, Philadelphia, Pennsylvania. The Exposition Auditorium was located south of the University of Pennsylvania, and the later Convention Hall was constructed along the building's east wall. It was demolished in 2006. Each state was allotted two delegates per electoral vote, and territories were granted from two to six delegates. Altogether, there were 926 delegates and an equal number of alternates. Mark Hanna opened the convention, and proposed that Senator Edward O. Wolcott of Colorado serve as temporary chairman: this was to show that the party had overcome its division in 1896, when the Colorado delegation walked out of the Republican Convention after a dispute over federal subsidies for the silver industry. Senator Henry Cabot Lodge of Massachusetts served as the convention's permanent chairman. President William McKinley was unanimously nominated for reelection after no candidate ran against him, although Admiral George Dewey considered a run. Governor Theodore Roosevelt of New York, who was himself a delegate, was nominated for vice president by a vote of 925 to zero, his vote alone abstaining.

State delegates

The 1900 Republican National Convention included a historic first for the Republican Party: Frances Warren of Wyoming served as the party's first-ever female convention delegate. Additionally Jennie L. McCargar Jones, of Utah, and Susan Henderson West of Idaho served as alternate delegates.
