The 1880–81 United States Senate elections were held on various dates in various states, coinciding with the presidential election of 1880. 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 1880 and 1881, and a seat may have been filled months late or remained vacant due to legislative deadlock.^[2] In these elections, terms were up for the senators in Class 1.

The Democratic Party lost five seats. The newly elected Readjuster senator William Mahone caucused with the Republicans, and the Republican Vice President's tie-breaking vote gave the Republicans the slightest majority. This changed when Vice President Chester Arthur ascended to the Presidency on September 19, 1881: with the Vice Presidency vacant during the remainder of Arthur's term, the Senate became evenly divided for the first of three times in history.

The New York election was held January 18, 1881, by the New York State Legislature. Democrat Francis Kernan had been elected in January 1875 to this seat, and his term would expire on March 3, 1881. At the State election in November 1879, 25 Republicans and 7 Democrats were elected for a two-year term (1880-1881) in the State Senate. At the State election in November 1880, 81 Republicans and 47 Democrats were elected for the session of 1881 to the Assembly. The 104th State Legislature met from January 4, 1881, on at Albany, New York.

The caucus of Republican State legislators met on January 13, State Senator Dennis McCarthy presided. All but one of the legislators were present, only State Senator Edward M. Madden (13th D.) was absent. The caucus nominated Ex-Congressman Thomas C. Platt for the U.S. Senate. Platt was a friend of the other U.S. Senator from New York, Roscoe Conkling, and belonged to the Stalwart faction. The opposing Half-Breeds (in the press sometimes referred to as the "anti-machine men") at first wanted to nominate Chauncey M. Depew, but he withdrew before balloting. The majority of the Half-Breeds, led by President pro tempore of the State Senate William H. Robertson, then supported Platt, a minority voted for Sherman S. Rogers, the defeated Republican candidate for Lieutenant Governor of New York in 1876. Congressman Richard Crowley was supported by a faction led by Speaker of the State Assembly George H. Sharpe, allied with Governor Alonzo B. Cornell. U.S. Vice President William A. Wheeler, and Congressmen Elbridge G. Lapham and Levi P. Morton also received votes.

The caucus of the Democratic State legislators met on January 17, State Senator Charles A. Fowler (14th D.) presided. They re-nominated the incumbent U.S. Senator Francis Kernan by acclamation.

Thomas C. Platt was the choice of both the State Senate and the Assembly, and was declared elected.

Notes:

• The votes were cast on January 18, but both Houses met in a joint session on January 19 to compare nominations, and declare the result.
• State Senator Stevens (Dem., 22nd D.) was absent and did not vote.
