The Luso-Sundanese padrão is a padrão commemorating a treaty between the kingdoms of Portugal and Sunda, better known as the Luso-Sundanese Treaty of Sunda Kalapa.

A padrão is a stone pillar left by Portuguese maritime explorers in the 15th and 16th centuries to record significant landfalls and thereby establish primacy and possession. They were often placed on promontories and capes or at the mouths of major rivers. Early markers were simple wooden pillars or crosses but they deteriorated quickly in the tropical climate where they were often erected. Later, padrões were carved from stone in the form of a pillar surmounted by a cross and the royal coat of arms.
