1855 United States Senate election in New York

The 1855 United States Senate election in New York was held on February 6, 1855, by the New York State Legislature to elect a U.S. Senator (Class 3) to represent the State of New York in the United States Senate.

Background
William H. Seward had been elected in 1849 to this seat and his term would expire on March 3, 1855.

At the time the Democratic Party was split into two opposing factions: the "Hards" and the "Softs". After most of the "Barnburners" had left the party, joining the Whigs, the majority of "Hunkers" split over the question of reconciliation with the minority of Barnburners who had remained Democrats. The Hard faction (led by Daniel S. Dickinson) was against it, in true Hunker fashion claiming all patronage for themselves; the Soft faction (led by William L. Marcy), which included the former Barnburners, advocated party unity as a necessity to defeat the Whigs.

In 1854, the Republican Party was founded as a national party, but in New York the Whigs and the Anti-Nebraska Party ran concurrently at the State election. The unification of these occurred in New York only during the nomination convention for the State election in November 1855. Also running in the 1854 election were the American Party and nominees of the Temperance movement. In a general way, party lines were blurred until the re-alignment during the late 1850s after the disbanding of the American Party.

At the State election in November 1853, 23 Whigs, 7 Hards and 2 Softs were elected for a two-year term (1854-1855) in the State Senate. At the State election in November 1854, Whig State Senator Myron H. Clark was elected Governor of New York, and 82 Whigs, 26 Softs, 16 Hards and 3 Temperance men were elected for the session of 1855 to the New York State Assembly. "Know Nothings are sprinkled miscellaneously among Whigs, Hards and Softs; and exactly how many there are of these gentry in the Assembly Nobody Knows." The 78th New York State Legislature met from January 2 to April 14, 1855, at Albany, New York.
