Viceré Marchese Francesco Jacomoni di San Savino (31 August 1893 – 17 February 1973) was an Italian diplomat and minister to Albania before World War II.

Named Lieutenant of Fortress Artillery in June 1915, Jacomoni participated in the campaigns of the Italian Front of World War I.

In October 1919 he was appointed as secretary in the Italian embassy at Bucharest, a post he held until recalled to the Ministry of Foreign Affairs in August 1920.

He was replaced with General Alberto Pariani on 18 March 1943, after his policy of severe repression had failed to halt the growth of the Albanian Resistance movement.

[3] After the war, he was tried along with other senior officials of the Fascist regime, and sentenced by the Italian High Court to 24 years imprisonment on 12 March 1945.
