The Italian Liberal Party (Italian: Partito Liberale Italiano; PLI) is a minor liberal political party in Italy, which considers itself to be the successor of the original Italian Liberal Party (PLI), the Italian main centre-right liberal party that was active in different capacities from 1922 to 1994. Originally named the Liberal Party (Partito Liberale), the new PLI changed its name in 2004. It is not represented in the Italian Parliament.

In July 1997 former members of the Italian Liberal Party (PLI) and, mostly, of the Union of the Centre (UdC), that is to say PLI's main successor, as well as some former Republicans formed the Liberal Party (PL). Most of its leading figures were also members of Forza Italia (FI): Stefano De Luca, Carlo Scognamiglio, Egidio Sterpa, Ernesto Caccavale, Luigi Caligaris and Guglielmo Castagnetti. Scognamiglio was a former President of the Senate (1994–96), De Luca, Caccavale and Caligaris MEPs, while Sterpa would have been elected to the Chamber of Deputies for FI in 2001.

In December 2004 the party was merged with other liberal groups and, as result, its name was changed to Italian Liberal Party (PLI), along with the claim of being the successor of the historical PLI, disbanded in 1994. At that point the party was completely enfranchised from FI and the centre-right House of Freedoms coalition, even though Sterpa continued to be a deputy within FI's parliamentary group.

In the 2006 Italian general election the PLI shortly rejoined the House of Freedoms. Being present only in a few regions, it obtained 0.3% of the vote.

In June 2007, during a party congress, the PLI reaffirmed its autonomy and De Luca was unanimously re-elected secretary. Additionally, some leading former Liberals joined (or re-joined) the party: Carlo Scognamiglio (PLD), Luigi Compagna (UDC) and Luciano Magnalbò (DLI/AN).

For the 2008 general election the PLI tried to form an electoral pact with the Union of Christian and Centre Democrats (UDC), but finally chose to run as a stand-alone list. Running in a few constituencies, the party obtained 0.3% of the vote and no seats.

In February 2009 the PLI held another congress. Arturo Diaconale, supported by Angelo Caniglia, a group of Liberal Reformers (including Marco Taradash, Emilia Rossi, Carlo Monaco and Pietro Milio) and other newcomers, presented his candidacy for secretary in opposition to De Luca, who was supported by the old guard and by Paolo Guzzanti, a dissenting member of Forza Italia and former Socialist. De Luca was re-elected with the support of 73% of the delegates, Guzzanti was appointed deputy secretary and Scognamiglio president. Diaconale left the party and would later revive the Italian Liberal Right (DLI), along with Giuseppe Basini.

In December 2010 Guzzanti left the party over personal problems with De Luca and became briefly engaged with the New Pole for Italy (NPI). In March 2011 the party was joined by two former secretaries of the old PLI, Alfredo Biondi, who had represented FI in Parliament from 1994 to 2006, and Renato Altissimo.
