Leopoldo Piccardi (Ventimiglia, 12 June 1889 – Rome, 18 April 1974) was an Italian politician and civil servant, who served as Ministry of Industry and Commerce of the Badoglio I Cabinet, the first after the fall of the regime.

[3] In November 1943 he resigned from his post as minister to enlist as an artillery captain in the Italian Co-belligerent Army until September 1944, when he was recalled and appointed extraordinary commissioner of the Istituto per la Ricostruzione Industriale.

[6][7] Popular Unity ran in the political elections of 7 June 1953, obtaining a modest result and no seats, but sufficient to prevent the parties of the government coalition from reaching the quorum required for the majority prize.

[8] On 28 November 1954 Piccardi was elected to the executive committee of the movement, together with Tristano Codignola, Ferruccio Parri, Paolo Battino Vittorelli and Oliviero Zuccarini.

[16][17][18] In December 1961 Mario Pannunzio and other members of the "Friends of Il Mondo" condemned Piccardi, asking for his resignation from the Radical Party, while Ernesto Rossi and Ferruccio Parri supported him.
