The Italian Associations in South America (Associazioni Italiane in Sud America, AISA) was a political party in Italy that represented voters living in South America, reflecting the significant Italian immigration to the continent.

Luigi Pallaro represented the party in the Senate while Ricardo Antonio Merlo represented it in the Chamber of Deputies until 2008, when he left to establish the Associative Movement Italians Abroad.

The Union, having just two more seats than the rival House of Freedoms, Pallaro did not formally declare a preference for either side.

However, he generally aligned with the centre-left government of Romano Prodi.

Pallaro's political career came to an end when he was not re-elected in the 2008 general election.
