Leganes is a 4th class municipality in the province of Iloilo, Philippines. It is located 11 km north of the capital Iloilo City. Like most Philippine towns that sprawl outward from the capital, is made up of houses, farms and light agricultural industry. The major throughofare runs right through the center of the town. According to the 2000 census, it has a population of 23,475 people in 4,533 households.

Leganes is politically subdivided into 18 barangays.

The town of Leganes sprang from a small settlement in the early part of 1840 in the site now known as Barangay Guihaman. The word guihaman originated from the presence of wild boars or guiham which inhabited and foraged the place.

The early founders of the municipality named the place Valencia in honor of its patron saint, San Vicente Ferrer of Valencia, a town in Spain. Learning the existence of the settlement, Don Ysidro A. Brudit, the Spanish Governor of Iloilo at that time, decreed sometime in 1856, that the settlement be registered as a pueblo otherwise a fine of P 600.00 will be levied on its inhabitants. In compliance with the decree, the place was registered as a pueblo in 1858.
