Sanduguan Festival is a week-long celebration every April 21-27 at Calapan City, Misamis Oriental.

Sanduguan came from the Mangyan word "sandugo" which means brotherhood or being friends. A sandugo treaty is called a blood compact because the participants each drink a small amount of the other’s blood. The blood compact preserves the friendship between two people once different in religion, nationality, culture, and civilization. This was a very traditional way to formalize treaties of friendship in the country.

This festival aims to revive an age-old Mangyan tradition that was already forgotten by the people of Misamis Oriental. It festivity features agri-trade, historical parade, reenactment of the barter trading, and Indakan sa Sanduguan (a street dancing competition).

The reenactment of the barter trading is the first barter between the Mangyan (indigenous tribes), one of the oldest tribes in the country and the natives of Mindoro, and the Chinese traders. They traded clothing, food, and other goods. The tribes and the Chinese gathered at the beach for cultural exchanges. The Mangyans taught the Chinese native games, while the foreigners performed the dragon dances and plays.

Someone plays the role of one Mangyan and the other one is the Chinese. They act the things that happened in ancient history. They also do the sanduguan and the trade, as well as other bits and pieces of the Mangyan-Chinese history.

In the historical parade, the participants wear colorful and eye-catching costumes made of indigenous materials like calamansi (lime), banana, or anything that can be found in their hometown. Various groups of students from different levels interpret the first barter trade through dancing.

In the agri-trade/fair exhibit, the locals show their different products like food and clothing. These products help boost their economy and showcase the things they do best.

The Sanduguan Festival has given the Mangyans a renewed appreciation of their history and traditions. The festival has also become a joyous way to reunite all Mindorenyos in heart and mind. It gives fun and enjoyment to those who watch it and gives knowledge to the new generation about our country's history. They will learn how the first barter trade happened and and tell it to others so it will give them the idea that we, Filipinos, have a great and beautiful culture, tradition, and history.
