Henry Smith (March 14, 1829 in Cobleskill, Schoharie County, New York – December 1, 1884) was an American lawyer and politician.
He was the son of Thomas Smith, a lawyer.
In 1865, he was elected District Attorney of Albany County, and in 1868 he led the prosecution of George W. Cole (brother of Cornelius Cole) at his trial for the murder of former state assemblyman L. Harris Hiscock.
He was a Republican member of the New York State Assembly (Albany Co., 2nd D.) in 1867 and 1872; and was Speaker in 1872. During his Speakership he received a large retainer for legal services rendered to the Erie Railroad at a time when Erie Railroad bills were under debate, which led to accusations that he was bribed to support the bills. The next year a State Senate Investigating Committee probed into this matter.
In 1883, he pronounced his opinion that a "People's Party" should be formed by both Democratic and Republican politicians to oppose "corporate interests" and politicians like John Kelly and John F. Smyth.
