The 1972 United States Senate election in Oregon took place on November 7, 1972. Incumbent Republican Senator Mark Hatfield was re-elected to a second term in office, defeating Democrat Wayne Morse.
Primary elections were held on May 23, 1972.
According to the New York Times, the election provided "a choice between two well-known personalities, not issues".[4] Morse, who had supported Hatfield's 1966 campaign, was famously opposed to the Vietnam War, as was Hatfield. Thus, the election was ultimately between two well-known anti-war liberals. Hatfield won a fairly comfortable 54-46 victory, winning all but 3 counties.
