Bayaguana is a municipality (municipio) of the Monte Plata province in the Dominican Republic.

Bayaguana was founded in 1606, when Spain resettled colonists from the northern and western part of Hispaniola closer to Santo Domingo, under the government eviction programme known as the devastations of Osorio.

Spanish colonists from La Yaguana and Bayajá (present-day Léogâne and Fort-Liberté, Haiti) were resettled in the town.

It operates the agricultural line, as well as part of its land is sown with sugar cane, pineapple and natural pastures for food for the cattle that it has in abundance.

It is the Salto de Comate, in the river of the same name, where hundreds of people flock every day to enjoy a bath in its cold waters.
