Smith Mead Weed (July 26, 1833 – June 7, 1920) was a Democratic lawyer and businessman from Plattsburgh, New York who served as a member of the New York State Assembly from 1865 to 1867, in 1871, and again in 1873 and 1874. Weed attended several Democratic National Conventions as a delegate and was a supporter of Samuel J. Tilden for president in 1876 and 1880. During the controversy that followed the disputed 1876 election, Weed was accused of attempting to bribe election officials in contested states in order to procure their support for Tilden.
