Francis Joseph Reitz (1841–1930) was an American banker, civic leader, and philanthropist in Evansville, Indiana.

After he retired, he devoted his time to disposing through philanthropy of the vast wealth he had accumulated.

His obituary cited that Reitz was a gentleman of the "old school" and preferred to avoid public attention.

Reitz gave millions of dollars to various charities, churches, and educational organizations.

At the dedication of the Catholic school — founded in 1922 on the city's east side — Bishop Joseph Chartrand of Indianapolis arrived as the emissary of the pope to bestow on Reitz the title of Commander of the Order of Pius IX.
