Sésia (French: [sesja]) was a department of the First French Republic and of the First French Empire in present-day Italy. It was named after the river Sesia. It was formed in 1801, when the Subalpine Republic (formerly the mainland portion of the Kingdom of Sardinia) was intended to be annexed to France. Its capital was Vercelli.

The department was disbanded after the defeat of Napoleon in 1814. At the Congress of Vienna, the Savoyard King of Sardinia was restored in all his previous realms and domains, including Piedmont. Its territory is now divided between the Italian provinces of Vercelli and Biella.
