The United States Senate elections of 1848 and 1849 were elections which had the Democratic Party lose seats but maintain control of the United States Senate.

As this election was prior to ratification of the seventeenth amendment, Senators were chosen by State legislatures.

The New York election was held February 6, 1849. Barnburner John Adams Dix had been elected in 1845 to this seat after the resignation of Silas Wright, and Dix's term would expire on March 3, 1849. In November 1848, Dix was the Barnburners/Free-Soilers candidate for Governor of New York, but was defeated by Whig Hamilton Fish.

At this time New York Democratic Party was split in two fiercely opposing factions: the Barnburners" and the "Hunkers". The Barnburners organized the Free Soil Party in 1848 and nominated Martin Van Buren for U.S. President. Due to the split, the Whig Party won most of the elective offices by pluralities.

At the State election in November 1847, 24 Whigs and 8 Democrats were elected for a two-year term (1848-1849) in the State Senate. At the State election in November 1848, 106 Whigs, 15 Free Soilers and 7 Hunkers were elected to the Assembly for the session of 1849. The 72nd New York State Legislature met from January 2 to April 11, 1849, at Albany, New York.
