Lombardy elected its third delegation to the Italian Senate on May 25, 1958. This election was a part of national Italian general election of 1958 even if, according to the Italian Constitution, every senatorial challenge in each Region is a single and independent race.

Lombardy obtained two more seats to the Senate, following the redistricting subsequent to the 1951 Census.

The election was won by the centrist Christian Democracy, as it happened at national level. All Lombard provinces gave a majority or at least a plurality to the winning party.

Even if Amintore Fanfani's Christian Democracy weakened in this election, Lombardy remained a stronghold for the national leading party.

As it happened five years before, the Communists obtained some seats in the agricultural south, while the Socialists remarked their strength in the Milanese industrial neighbourhood. The centre-left Italian Democratic Socialist Party obtained two seats in Milan, a city led by Democratic Socialist mayor Virgilio Ferrari, while the rightist Italian Social Movement and the Italian Liberal Party obtained some good results in the bourgeois center of Milan.

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.

• 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 (always a Christian democrat) with more votes in their constituency.
