Lake Iseo or Iseo lake (US: /iːˈzeɪoʊ/ ee-ZAY-oh;[1] Italian: Lago d'Iseo Italian pronunciation: [ˈlaːɡo diˈzɛːo]; Eastern Lombard: Lach d'Izé), also known as Sebino (Italian: [seˈbiːno]; Latin: Sebinus), is the fourth largest lake in Lombardy, Italy, fed by the Oglio River.

It is in the north of the country in the Val Camonica area, near the cities of Brescia and Bergamo.

Northern Italy is known for its heavily industrialised towns and in between there are several natural lakes.

[2] The Floating Piers, an art installation by Christo and Jeanne-Claude (made of a series of walkways), was open to the public at Lake Iseo for 16 days in June and July 2016.

The work, built in concrete and steel, is managed by the Consorzio dell'Oglio which divides the water withdrawn between irrigation uses and hydroelectric uses.
