Maria Cristina Falls is a waterfall of the Agus River on the island of Mindanao. It is sometimes called the "twin falls" as the flow is separated by a rock at the brink of the waterfall. It is a landmark of Iligan City, nicknamed the City of Majestic Waterfalls, because of the presence of more than 20 waterfalls in the city. It is located 9.3 kilometers away southwest of the city proper at the boundaries of Barangays Maria Cristina, Ditucalan, and Buru-un.

Well-known for its natural beauty and grandeur, the 320 - feet (98 meters) high waterfall is also the primary

source of electric power for the city's industries, being harnessed by the Agus VI Hydroelectric Plant.

Under President Gloria Macapagal-Arroyo's Mindanao Super Region development plan, the Agus VI is planned

to undergo a 1.856-billion-peso upgrading project.
