The 1867 United States Senate election in California was held on December 20, 1867, by the California State Legislature to elect a U.S. Senator (Class 1) to represent the State of California in the United States Senate. In a special joint session, former Democratic State Printer Eugene Casserly was elected over fellow Democratic former Congressman from Illinois Joseph P. Hoge.[1] Casserly and Hoge opposed each other over a dispute regarding an alleged deal that Hoge would let Casserly's protege Henry Huntly Haight run for Governor in exchange for Casserly backing Hoge for Senator.[2]
