The 1999 European Parliament election in Italy was the election of the delegation from Italy to the European Parliament in 1999.
The pure party-list proportional representation was the traditional electoral system of the Italian Republic since its foundation in 1946, so it had been adopted to elect the Italian representatives to the European Parliament too. Two levels were used: a national level to divide seats between parties, and a constituency level to distribute them between candidates. Italian regions were united in 5 constituencies, each electing a group of deputies. At national level, seats were divided between party lists using the largest remainder method with Hare quota. All seats gained by each party were automatically distributed to their local open lists and their most voted candidates.
Seats are allocated to party lists on a national basis using an electoral quota, with the residue given to the lists with the largest excess over whole quotas. An electoral quota is then calculated for each list and used to allocate seats to each list in each of the five electoral regions.
The election was won again by Forza Italia (FI), which had joined the European People's Party (EEP), with 25.2% of the votes and 22 seats. The governing Democrats of the Left (DS), led by Walter Veltroni, got 17.3% of the vote and 15 seats, while National Alliance (AN), federated to the Segni Pact (PS), got 10.3% of the vote and 9 seats (8 seats to AN and one seat to PS). A good result was also obtained by the Bonino List (LB), which gained 8.5% of the vote and 7 seats.
