Horace Boies (December 7, 1827 – April 4, 1923) served as the 14th Governor of Iowa from 1890 to 1894 as a member of the United States Democratic Party.

Moving back to New York, he studied law and was admitted to the bar in 1849, setting up practice in Hamburg, near Buffalo.

He was elected governor of Iowa as a Democrat in 1889, breaking longtime Republican dominance of state politics.

He was a prominent populist and advocate of bimetallism, and during his term as governor proclaimed Iowa's first Labor Day holiday.

This was a popular destination for Iowans at the time, and Boies was active in social events of his fellow Iowan transplants, participating in the Long Beach Iowa Reunion and serving as president of the Long Beach Iowa Association.
