Bầu cử tổng thống Hoa Kỳ tại Louisiana năm 1968

The 1968 United States presidential election in Louisiana was held on November 5, 1968, as part of the 1968 United States presidential election. Along with four other contiguous southern states, former and future Alabama Governor George Wallace won the state for the American Party by a large margin against Democrat Hubert Humphrey and Republican Richard Nixon. As of the 2024 presidential election, this is the last election in which Jefferson Parish, St. Tammany Parish, Lafayette Parish, Ouachita Parish, Bossier Parish, Union Parish, and LaSalle Parish did not vote for the Republican presidential candidate.

With 48.32% of the popular vote, Louisiana would prove to be Wallace's third strongest state after Alabama and Mississippi. This is the most recent election cycle in which a Republican would win the presidency without carrying Louisiana. This was also the last election until 2008 in which Louisiana voted for a losing presidential candidate.
