Bầu cử tổng thống Hoa Kỳ tại Connecticut năm 1964

The 1964 United States presidential election in Connecticut took place on November 3, 1964, as part of the 1964 United States presidential election, which was held throughout all 50 states and D.C. Voters chose eight representatives, or electors to the Electoral College, who voted for president and vice president.

Connecticut voted overwhelmingly for the Democratic nominee, incumbent President Lyndon B. Johnson of Texas, over the Republican nominee, Senator Barry Goldwater of Arizona. Johnson ran with Senator Hubert H. Humphrey of Minnesota, while Goldwater's running mate was Congressman William E. Miller of New York.

Johnson carried Connecticut by a wide margin of 35.72%. His 67.81% vote share is the largest for a Democrat in Connecticut presidential election history, and the largest for any party since John Quincy Adams in 1828. He was the first Democrat to win every county since 1852.

To date, this is the last time that the city of Shelton and the towns of Bethlehem, Goshen, Harwinton, Middlebury, New Fairfield, Oxford, and Somers voted Democratic.

In addition, this election marks the last time that any presidential candidate won more than 70% in any Connecticut county.
