Adolfo Sevilla Azcuna (born February 16, 1939) is a Filipino jurist who served as an Associate Justice of the Supreme Court of the Philippines from 2002 to 2009.

He was succeeded by Arturo Brion who served for 2 years[1] and was replaced by Rosmari Carandang as the fourth Chancellor[2] who took her oath on February 23, 2022.

On January 8, 2013, the Junior Chamber International (JCI) Senate Philippines and the Insular Life Assurance Co., Ltd. conferred to Justice Azcuna The Outstanding Filipino (TOFIL) Award for 2012 in the field of Justice/Law.

[2] The citation stated: "For living as a selfless public servant who puts country before self and as a man of deep faith whose devotion to his family is unchanging; for devoting more than 50 years of his life to judicial work, driven by a commitment to the delivery of justice; for ensuring the protection of every Filipino's constitutional right to life, liberty, and security through the writ of amparo; for lighting a path of excellence, service, and probity that young Filipinos and Ateneans may follow.

The Court granted the petition of two foundations that sought to block Gregory S. Ong’s appointment over the citizenship issue.

Azcuna wrote that Ong would be unable to join them on the bench "until he had proven in court that he was a natural-born Filipino citizen and corrected the records of his birth and citizenship".
