Dipolog City Day, observed in the Philippines, is celebrated every July 1 to commemorate the anniversary of Dipolog's establishment as a municipality during American rule. This special non-working holiday features various cultural and sports activities, award ceremonies, and other events that highlight the city's heritage. Dipolog, known as the capital of Zamboanga del Norte and nicknamed the “Orchid City of the Philippines” and the “Bottled Sardines Capital of the Philippines,” has a rich history dating back to the 12th century with the settlement of the Subanen people. The area was officially recognized in 1834, and after several developments, it regained its status as a municipality on July 1, 1912. The holiday serves as a reminder of Dipolog's journey from a barrio of Dapitan to an independent city, officially established in 1970.
