The Parti Socialiste Unifi‚ (PSU) is a political party in France. It was founded in 1960 as a breakaway from the French Socialist Party, and has been active in French politics since then. The party is considered to be on the left-wing of the political spectrum, and its platform includes issues such as social justice, environmental protection, and equality. The PSU has had some electoral success in the past, but it has not been a major player in national politics in recent years. It is currently a member of the European Democratic Party, a centrist political group in the European Parliament.
