- Source: 1972 Italian Senate election in Lombardy
Lombardy elected its sixth delegation to the Italian Senate on May 19, 1972. This election was a part of national Italian general election of 1972 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. Seven Lombard provinces gave a majority or at least a plurality to the winning party, while the agricultural Province of Pavia and Province of Mantua preferred the Italian Communist Party.
Background
This election was quite a copy of the previous one. The Italian Liberal Party was the sole loser, to its left to the Italian Republican Party and to its right to the Italian Social Movement.
Electoral system
The electoral system for the Senate was a strange hybrid which established a form of proportional representation into FPTP-like constituencies. A candidate needed a landslide victory of more than 65% of votes to obtain a direct mandate. All constituencies where this result was not reached entered into an at-large calculation based upon the D'Hondt method to distribute the seats between the parties, and candidates with the best percentages of suffrages inside their party list were elected.

= Constituencies
=Senators with a direct mandate have bold percentages. Please remember that the electoral system was, in the other cases, a form of proportional representation and not a FPTP race: so candidates winning with a simple plurality could have (and usually had) a candidate (usually a Christian democrat) with more votes in their constituency.
= Substitutions
=Carlo Porro for Cantù (7.2%) replaced Virginio Bertinelli in 1973. Reason: death.
Leonello Zenti for Mantua (35.7%) replaced Faustino Zugno in 1975. Reason: death.
