The Italian Socialists were a minor social-democratic political party in Italy active from 1994 to 1998. The party was the legal successor of the Italian Socialist Party (PSI), following its dissolution by the 47th Party Congress due to the severe financial crisis following the Tangentopoli scandal. A minoritarian group of the congress, who proposed an autonomist and centrist solution against the PSI dissolution, instead founded the Reformist Socialist Party.

The Italian Democratic Socialist Party, also known as Italian Social Democratic Party, was a social-democratic political party in Italy. The longest serving partner in government for Christian Democracy, the PSDI was an important force in Italian politics, before the 1990s decline in votes and members. The party's founder and longstanding leader was Giuseppe Saragat, who served as President of the Italian Republic from 1964 to 1971. Compared to the like-minded Italian Socialist Party on the centre-left, it was more centrist, but it identified with the centre-left.
