66th New York State Legislature
The 66th New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from January 3 to April 18, 1843, during the first year of William C. Bouck's governorship, in Albany.

Background
Under the provisions of the New York Constitution of 1821, 32 Senators were elected on general tickets in eight senatorial districts for four-year terms. They were divided into four classes, and every year eight Senate seats came up for election. Assemblymen were elected countywide on general tickets to a one-year term, the whole Assembly being renewed annually.

On April 5, 1842, the Legislature enacted that future state elections be held on a single day, fixing the date on the Tuesday next after the first Monday in November.

State Senator John W. Taylor resigned on August 19, 1842, leaving a vacancy in the Fourth District.

At this time there were two major political parties: the Democratic Party and the Whig Party. The radical abolitionists appeared as the Liberty Party.

On September 7, 1842, the Democratic state convention met at Syracuse, and nominated again William C. Bouck for governor, and Daniel S. Dickinson for lieutenant governor.

On the same day, the Whig state convention nominated Lt. Gov. Luther Bradish for governor, and State Senator Gabriel Furman for lieutenant governor.

The Liberty Party nominated Alvan Stewart for governor, and Charles O. Shepard for lieutenant governor.

Elections
The state election was held on November 8, 1842. William C. Bouck and Daniel S. Dickinson were elected governor and lieutenant governor.

Abraham A. Deyo (2nd D.), John C. Wright (3rd D.), Sidney Lawrence, Thomas B. Mitchell (both 4th D.), Calvin T. Chamberlain (6th D.), John Porter (7th D.), Harvey Putnam (8th D.), and assemblymen John A. Lott (1st D.) and Carlos P. Scovil (5th D.) were elected to the Senate. Putnam was a Whig, the other eight were Democrats.

Sessions
The Legislature met for the regular session at the Old State Capitol in Albany on January 3, 1843; and adjourned on April 18.

George R. Davis (D) was elected Speaker with 89 votes against 32 for Willis Hall (W). Henry N. Wales (D) was elected Clerk of the Assembly with 91 votes against 35 for Philander B. Prindle (W).

On January 21, the Legislature elected Edwin Croswell (D) to succeed Thurlow Weed as State Printer.

On February 6, the Legislature re-elected State Treasurer Thomas Farrington (D).

On February 7, the Legislature re-elected U.S. Senator Silas Wright, Jr. to a six-year term beginning on March 4, 1843.
