The election took place midway through Chris Christie's first term as Governor of New Jersey.

No seats changed hands, though Democrats had gained one seat in a 2010 special election with Linda Greenstein's victory over Tom Goodwin.

This was the first election under maps drawn after the 2010 census.

Three incumbents retired from the Senate including Sean Kean, who was redistricted into Jennifer Beck's district and ran for Assembly rather than challenge her.
