Cosalá (Spanish pronunciation: [kosa'la] ⓘ) is a small city and the seat of its surrounding municipality in the Mexican state of Sinaloa.

The Museum of Mineralogy mainly displays photographs and documents on the history of mining in Sinaloa.

Cosalá was the dominant region in the social and political life of the State of Sinaloa until it became its capital in the early independent Mexico.

Most municipalities to the north of Cosalá, such as Culiacán, have semi-arid to arid climates, as one moves towards the Sonoran–Sinaloan transition subtropical dry forest, and into the Sonoran Desert.

Cosalá, Sinaloa, was named a "Pueblo Mágico" in 2005 for its natural environment, cultural riches, and historical relevance.
