The United States Senate election of 1934 in New Jersey was held on November 6, 1934.
Incumbent Republican Senator Hamilton Fish Kean ran for re-election to a second term in office, but was defeated by Governor of New Jersey A. Harry Moore in a landslide.
This was among the nine seats Democrats gained in this year's elections.
This election also marks the end of a streak of four straight elections in which the incumbents were defeated, beginning in 1916.
Senator Kean was challenged by former Assemblyman James Blauvelt, who opposed what he called Kean's "Wall Street viewpoint." The opposition came as a surprise to the Senator and most Republicans.[2] He ran on a ticket named "Public Ownership; Against Wall St. Domination."[2]
