Marengo is the name of a département of the consulate and of the First French Empire in present Italy. It was named after the Marengo ("Marengh" in piedmontese) plain near Alessandria to commemorate the Battle of Marengo (1800). The capital was Alessandria and the other principal cities were Asti, Bobbio, Casale Monferrato, Tortona and Voghera. The department was suppressed following the defeat of Napoleon in 1814 and the restoration of his Piedmontese territories to the King of Sardinia.
It was formed in 1802 when Napoleon Bonaparte occupied Piedmont. Initially it comprised the former Piedmontese provinces of Alessandria, Casale, Tortona, Voghera and Bobbio. Following the annexation of the Ligurian Republic to France in 1805, Voghera, Bobbio and Tortona passed to the newly created Department of Genoa, while the Department of Marengo acquired Asti, previously in the Department of Tanaro. The département was subdivided into the following arrondissements and cantons (situation in 1812):
- Alessandria, cantons: Alessandria (2 cantons), Bosco, Cassine, Castellazzo, Felizzano, Sezzadio and Valenza.
- Asti, cantons: Asti, Canelli, Castelnuovo d'Asti, Cocconato, Costigliole, Mombercelli, Montafia, Montechiaro, Portacomaro, Rocca d'Arazzo, San Damiano, Tigliole and Villanova d'Asti.
- Casale, cantons: Casale, Gabiano, Moncalvo, Montemagno, Montiglio, Pontestura, Rosignano, San Salvatore, Ticineto and Villanova.
Its population in 1812 was 318,447, and its area was 348,261 hectares.
The division was included within the 28th military division, the 16th cohort of the légion d'honneur, the 29th conservation des forêts, the Diocese of Casale, the sénatorerie of Turin and the court of appeal of Genoa. It elected three deputies to the Corps législatif of the First Empire.
