1818 United States House of Representatives elections in New York

27 U.S. Representatives had been elected in April 1816 to a term in the 15th United States Congress beginning on March 4, 1817. Representative-elect Henry B. Lee died on February 18, 1817, and James Tallmadge, Jr. was elected in April 1817 to fill the vacancy. The representatives' term would end on March 3, 1819. The congressional elections were held together with the State elections in late April 1818, about ten months before the term would start on March 4, 1819, and about a year and a half before Congress actually met on December 6, 1819.

The geographical area of the districts remained the same as at the previous elections in 1816. Two new counties were created: Tompkins inside the 20th District; and Cattaraugus inside the 21st District. In 1817, the Town of Danube was separated from the Town of Minden in Montgomery County, and transferred to Herkimer County, but Danube remained in the 14th District.

Note: There are now 62 counties in the State of New York. The counties which are not mentioned in this list had not yet been established, or sufficiently organized, the area being included in one or more of the abovementioned counties.

19 Democratic-Republicans, 6 Clintonian-Federalists[1] and 2 Federalists were elected to the 16th Congress. The incumbents Wendover, Tompkins, Taylor and Storrs were re-elected, the incumbent Ellicott was defeated.

Note: It is difficult to ascertain the party affiliation of these candidates: At this time began the split of the Democratic-Republican Party into two opposing factions: on one side, the supporters of DeWitt Clinton and his Erie Canal project; on the other side, the Bucktails (including the Tammany Hall organization in New York City), led by Martin Van Buren. At the same time, the Federalist Party had already begun to disintegrate. In the Southern districts the Federalists and Clintonians combined to vote for joint nominees, running against the Bucktails; in the Western districts, where the Erie Canal was under construction, the Democratic-Republican nominees were Clintonians who were elected unopposed.

The House of Representatives of the 16th United States Congress met for the first time at the reconstructed United States Capitol in Washington, D.C., on December 6, 1819, and 26 of the representatives took their seats. Only Ebenezer Sage did not appear.[10]

On December 10, Nathaniel Allen presented a petition on behalf of James Guyon, Jr. to contest the election of Ebenezer Sage in the 1st District. On January 12, 1820, the Committee on Elections submitted its report. They found that the election inspectors in the towns of Northfield (on Staten Island), Brooklyn, Hempstead and Oyster Bay had returned 391 votes for "James Guyon" although all these votes had in fact been given for "James Guyon, Jr."[11] The Secretary of State of New York, receiving the abovementioned result, issued credentials for Sage who never took or claimed the seat. On January 14, the House declared Guyon, Jr., entitled to the seat, and Guyon took it.[12]
