Putagán (in mapudungun: "water stream") is a village in the Chilean municipality of Villa Alegre, Province of Linares, Maule Region.
Its economy is based around agricultural activities like vineyards, rice, corn plantations, and lately berries for the European markets.
Around 1580, the then Bishop of Santiago de Chile, Fray Diego de Medellín, created two missions south of the Maule River that remained under the jurisdiction of the Santiago bishops for more than 170 years.
Between 1913 and 1954 Putágan was the starting point of the narrow gauge Putagán—Colbún railway terminating in the city of Colbún.
The Putagán River passes south of the village and forms the border of the municipalities of Villa Alegre and Linares.
