The To-og Tree is a giant Petersianthus quadrialatus tree located in Barangay Alegria, San Francisco, Agusan del Sur, Mindanao, Philippines. Estimated to be over 300 years old and standing more than 50 meters tall, it is considered one of the oldest and tallest trees in the Philippines. Recognized as a local heritage and ecotourism landmark, the tree is notable for its massive trunk, buttressed roots, and ecological importance as a native Philippine rosewood species.

The site is developed for viewing with a surrounding fence, viewing platform and information signage. The surroundings are rural and forested, offering an open area for sightseeing, photography and learning about native tree conservation.
