Buen Calubayan (b. 1980, Philippines) is a Manila-based artist that constructs worldviews through an interdisciplinary approach encompassing museology, pedagogy, and landscape theory. His installations incorporate paintings, diagrams, timelines, and archival pieces, aiming to navigate the complex and unstable Philippine landscape. Investigating the mechanisms of world-making and perception, Calubayan employs the Renaissance technique of linear perspective within the context of landscape painting and applies a diagrammatic approach to analyse 19th-century colonial paintings in the Philippines. This method involves rethinking concepts like the horizon, vanishing point, grounding, and the mechanisms making them visible, including framing, archiving historiography, and accessibility. Calubayan intertwines politics, religion, history, and identity in his practice. His work combines autobiographical and art historical elements, addressing the historical influence of Western canons on Filipino art and his personal struggles as an artist. Calubayan continues to contribute to the discourse on the socio-cultural histories of the Philippines.

Calubayan, a Cultural Heritage Studies major from the University of Santo Tomas, worked at UST Museum of Arts and Sciences and the National Museum of the Philippines. He participated in residencies in Australia, Japan, and Singapore from 2008 to 2018. He exhibits internationally including at institutions like the Metropolitan Museum of Manila and Gwangju Museum of Art. Recent solo shows include "Biowork" at Ateneo Art Gallery and "Idiot Knows No Country" at La Trobe University Visual Arts Center. Calubayan was recognised as the 2013 Ateneo Art Awards for the "Spoliarium" project and the 13 Artists Award in 2009 by the Cultural Centre of the Philippines.
