1813 United States House of Representatives elections in New Jersey

New Jersey kept its delegation at six seats but changed from electing its Representatives on a statewide general ticket to using three plural districts of two seats each. These districts were used only for the 1812 election, and the state returned to using a single at-large district in 1814. This was only the second time that New Jersey used districts (the first being in 1798).

There was a statewide at-large election held in November 1812, that was invalidated: "In October 1812, when the Federalists captured the State Legislature, both parties had already nominated their tickets for Presidential Electors and Congress. That election was scheduled for November 1812. However, … the Federalist[s], now controlling the legislature, changed the method of selecting Presidential Electors, from popular vote, to a choice by the Legislature and as a result the election for Presidential Electors was invalidated. In addition to changing the method of choosing Presidential electors, the Federalist also decided to alter the election of congressmen from state wide At-Large to Districts. The scheduled November elections were postponed and three separate Districts were created, each electing two Congressmen. This election was held January 12th and 13th 1813. Some towns, either because word of these changes did not reach them in time, or most likely in defiance, went ahead and held elections. The Republican ticket received almost all of the votes cast, with the Federalist getting only a single votes in two towns, which suggests they were protesting the changes made by the Legislature. These returns were never reported in the newspapers."
