The 1962 United States Senate election in Louisiana was held on November 6, 1962. Incumbent Democratic Senator Russell Long was elected to a fourth term in office. On August 17, Long won the Democratic primary with 80.15% of the vote. Long won the general election against Shreveport attorney , who staged a rare bid for statewide office on the Republican line. O'Hearn carried seven parishes in northern Louisiana, a sign of growing disenchantment by conservative Southern whites with the Kennedy administration, but Long still won an easy majority in a state that remained predominantly Democratic.
