Félix Valencia Makasiar (November 20, 1915 – February 19, 1992) was the 14th Chief Justice of the Supreme Court of the Philippines, serving in that capacity for four months in 1985. His 85-day stint as Chief Justice, abbreviated only because of the rule requiring mandatory retirement upon reaching the age of 70, was the second-shortest such tenure in Philippine history. Prior to his promotion as Chief Justice, Makasiar had served for 15 years as an Associate Justice.
