Partido ng Masang Pilipino (Party of the Filipino Masses) was the political party of former Philippine President Joseph Estrada, which merged with other political parties to create Laban ng Makabayang Masang Pilipino or LAMMP (Struggle of the Patriotic Filipino Masses) in the 1998 Presidential Elections. PMP was Estrada's party when he ran for a Senate seat in 1987 and made a coalition with Nationalist People's Coalition party in 1992 when Estrada ran as Vice President under tycoon Eduardo Danding Cojuangco's ticket. Today, PMP occupies two Senate seats as a member of the Minority floor, occupied by Estrada's wife, Luisa Ejercito Estrada , who won in 2001 and his son, former San Juan suburb Mayor Jose Jinggoy Estrada , who won in 2004.
