Marcello Soleri (28 April 1882 – 22 July 1945) was an Italian politician and an officer of the prestigious Alpini infantry corps. He is widely viewed as one of the leading exponents of political liberalism in twentieth century Italy. Soleri was a Member of Parliament between 1913 and 1929. During 1921/22 he served successively as Italian Minister of Finance and (more briefly) as Italian Minister of War. After the fall of Mussolini he returned to government in 1944 as Italian Minister of Treasury under Prime Minister Bonomi.
