The minority floor leader of the House of Representatives of the Philippines, or simply the House minority floor leader, is the leader elected by the minority bloc of the House of Representatives of the Philippines that serves as their official leader in the body. He also manages the business of the minority party in the Senate. He is expected to be vigilant in the defense of the minority's rights. It is his function and duty to criticize constructively the policies and programs of the majority, and to this end employ parliamentary tactics and give close attention to all proposed legislation.
Traditionally, the defeated contender in the speakership election becomes the minority leader, but the rules were amended for the 17th Congress with the minority bloc now electing their minority leader among themselves.
From 1907 to 1909, Vicente Singson Encarnación, a member of the Progresista Party, served as the minority floor leader of the newly-inaugurated Philippine Assembly during the 1st Philippine Legislature.
The Nacionalista Party, which was the historical ruling party in both houses of Congress in the early 1900s, served as the opposition party to the Liberal Party in the House from 1946 until 1953, after the Liberals won the majority of congressional seats in two consecutive elections. Nacionalista members Cipriano Primicias Sr. and Jose Laurel Jr. served as minority leaders in the 1st and 2nd Congresses, respectively.
On March 9, 1962, Daniel Romualdez of the Nacionalista Party was ousted from the speakership by Liberal Cornelio Villareal and served as minority leader during the 5th Congress.
