Lombardy elected its third delegation to the Italian Senate on April 28, 1963. This election was a part of national Italian general election of 1963 even if, according to the Italian Constitution, every senatorial challenge in each Region is a single and independent race. The election was won by the centrist Christian Democracy, as it happened at national level. Eight Lombard provinces gave a majority or at least a plurality to the winning party, while the agricultural Province of Pavia preferred the Italian Communist Party.
