Lanao del Norte Day, observed in the Philippines, is celebrated every July 4 to commemorate the founding anniversary of the province of Lanao del Norte. This special non-working holiday coincides with Philippine-American Friendship Day. Lanao del Norte, located in the Northern Mindanao region, was formally inaugurated on July 4, 1959, with Iligan as its capital. The celebration includes a week-long festival that showcases the culture and traditions of the province, highlighting the peaceful coexistence between its Christian and Muslim populations. Events during the festival feature a Thanksgiving mass, parades, the Miss Lanao del Norte beauty pageant, dance and sports competitions, and the Sagayan Festival, a cultural dance contest depicting the legendary chieftain Datu Bantugan. The province's economy is primarily based on fishing and agriculture, with Iligan City serving as its industrial center. Lanao del Norte Day was officially established in 2018, emphasizing the rich heritage and community spirit of the region.
