Autonomy Liberty Participation Ecology (French: Autonomie, Liberté, Participation, Écologie, ALPE) was a regionalist[2] political party active in Aosta Valley, Italy, whose progressive ideology mixes elements of social democracy[2] and green politics.

[3] ALPE was founded in January 2010 by the merger of five groups:[4][5][6][7] Carlo Perrin, a former senator, was elected first co-ordinator, later president, of the party.

[8] In the 2013 Italian general election ALPE was part of the Autonomy Liberty Democracy (ALD) coalition and ALPE's Patrizia Morelli stood for the Senate, but both ALD candidates (the other being Jean-Pierre Guichardaz of the Democratic Party) were defeated.

[11][12] In March 2017 ALPE, along with the Progressive Valdostan Union (UVP), Edelweiss (SA), and For Our Valley (PNV) formed a new cabinet without the Valdostan Union (UV), under President Pierluigi Marquis (SA).

After the election, the Regional Council elected Nicoletta Spelgatti of Lega Nord Valle d'Aosta (LNVdA) as President, at the head of a broad left-right coalition, comprising SA–PNV, ALPE, Mouv' and one defector from UV's ranks.
