The Naga City Charter Anniversary, observed in Naga City, Philippines, is celebrated every June 18. This special non-working holiday commemorates the day Naga was officially granted city status in 1948. Naga, a first-class independent component city in the Bicol Region, is known as the Heart of Bicol and the Queen City of Bicol. The city's name derives from the Bikol word for the narra tree, which has historical significance in the region. The anniversary is marked by official ceremonies and various events that honor Naga's rich history and culture, reflecting its evolution from a native village and Spanish settlement to a major center of trade and education during the colonial era. The celebrations highlight the city's legacy, including its role during the Philippine Revolution and World War II.
