The 1848–49 United States Senate elections were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1848 and 1849, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 3.

New York

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.

Ex-Governor of New York William H. Seward was nominated by a caucus of Whig State legislators on February 1, 1849. The vote was 88 for Seward, 12 for John A. Collier, 18 scattering and 4 blanks. The incumbent U.S. Senator John Adams Dix ran for re-election supported by the Free Soilers. Ex-Chancellor Reuben H. Walworth was the candidate of the Hunkers. Walworth had been third place in the last gubernatorial election, behind Fish and Dix. Ex-Congressman Daniel D. Barnard (Whig) received 2 scattering votes in the Senate. William H. Seward was the choice of both the Assembly and the Senate, and was declared elected.

House	Whig		Free Soil		Dem./Hunker		Also ran
State Senate (32 members)	William H. Seward	19	John Adams Dix	6	Reuben H. Walworth	2	Daniel D. Barnard	2
State Assembly (128 members)	William H. Seward	102	John Adams Dix	15	Reuben H. Walworth	7

Ohio

The two houses of the Ohio General Assembly met in joint session February 22, 1849, with 72 representatives and 35 senators present to elect a Senator (Class 3) to succeed incumbent William Allen. On the fourth ballot, Salmon P. Chase was elected with a majority of the votes cast, as follows:

Ballot	William Allen	Thomas Ewing	Joshua Reed Giddings	Salmon P. Chase	Reuben Hitchcock	Emery D. Potter	David T. Disney	John C. Vaughn	Blank ballots	Total votes cast
1	27	41	9	14	1	2	1	0	11	106

3	0	39	9	53	0	0	0	2	2	105
4	0	39	11	55	0	0	0	1	0	106

The second ballot was declared a nullity by Speaker of the Senate , because there were one more ballots cast than members present.

Pennsylvania

The Pennsylvania election was held January 10, 1849. James Cooper was elected by the Pennsylvania General Assembly.

Incumbent Democrat Simon Cameron, who was elected in 1845, was not a candidate for re-election to another term. The Pennsylvania General Assembly, consisting of the House of Representatives and the Senate, convened on January 10, 1849, to elect a new Senator to fill the term beginning on March 4, 1849. Three ballots were recorded. The results of the third and final ballot of both houses combined are as follows:

State Legislature results
Party		Candidate	Votes	%
	Whig	James Cooper	66	49.62
	Democratic	Richard Brodhead	62	46.62
