1960 United States presidential election in Oklahoma

The 1960 United States presidential election in Oklahoma took place on November 8, 1960, as part of the 1960 United States presidential election. Voters chose eight representatives, or electors, to the Electoral College, who voted for president and vice president.

Oklahoma was won by incumbent Vice President Richard Nixon (R–California), running with United States Ambassador to the United Nations Henry Cabot Lodge Jr., with 59.02% of the popular vote, against Senator John F. Kennedy (D–Massachusetts), running with Senator Lyndon B. Johnson, with 40.98% of the popular vote. In the Electoral College, Nixon received seven of Oklahoma's eight electoral votes; the eighth was cast by a faithless elector for Harry F. Byrd of Virginia.

The faithless elector was Henry D. Irwin (October 22, 1917 – September 3, 1988), a career U.S. Army officer and Republican political figure from Oklahoma. Irwin later admitted in a CBS interview that he "could not stomach" Nixon. After the November election, he sent telegrams to the other 219 Republican electors urging them to support a Byrd-Goldwater ticket as a conservative alternative to both Kennedy and Nixon, receiving about 40 replies but failing to convince any other elector to defect. Irwin was subsequently subpoenaed by a Senate committee to testify about his electoral vote after initially declining an invitation to appear voluntarily. Oklahoma Republican chair Henry Bellmon stated that Irwin had acted entirely on his own.

With 59.02% of the popular vote, Oklahoma would prove to be Nixon's third strongest state in 1960 after Nebraska and Kansas. This election marked the first time since statehood that a Democrat won the presidency without carrying Oklahoma. Oklahoma was one of six states that swung towards Republicans compared to 1956, alongside Alabama, Georgia, Mississippi, South Carolina, and Tennessee.
