Blood compact (in Spanish: Pacto de sangre) was a ritual in the Philippines where tribes would cut their wrist and pour their blood into a cup filled with liquid and drink each other's blood as part of the tribal tradition to seal a friendship, a pact or treaty, or to validate an agreement.

An example of the blood compact was called Sandugo, which took place in the island of Bohol in the 16th century. The ritual was made between the Spanish explorer Miguel López de Legazpi and Datu Sikatuna the chieftain of Bohol. A blood compact was also made between the Portuguese explorer Ferdinand Magellan and Rajah Humabon the chieftain of Cebu.
