Hiram Barney (May 30, 1811 – May 18, 1895) was Collector of the Port of New York from 1861 - 1864. He was born in Henderson, Jefferson County, New York and graduated from Union College in Schenectady, New York, in 1834. Barney was Collector during the first three years of the administration of Abraham Lincoln. He resigned and refused an appointment to a foreign mission.
In 1830 he served as chairman of the executive committee of the Young Men's Anti-Slavery Society in New York City. He was associated with John Jay, A.C. Coxe, Theodore Weld, and Henry Stanton. 1840 he formed a law partnership with William Mitchell in New York City. The firm was later continued under the name of Barney, Humphrey, and Butler. Mitchell died suddenly and in March 1849 Barney became associated with Benjamin Franklin Butler (lawyer) and his son William Allen Butler.
In 1840, he was nominated for the United States Congress by the Anti-Slavery Party. He was a presidential elector when the Free Soil Party was formed in 1848. Barney was a delegate to the Republican National Convention of 1856, which nominated John C. Fremont. He voted for Charles Sumner rather than Fremont while he was there. He attended the Republican National Convention in Chicago, Illinois in 1860. Barney met with Lincoln at Springfield, Illinois shortly after the convention ended. Barney raised $35,000 in New York, which he sent to the Illinois State Committee.
