Laban ng Makabayang Masang Pilipino (Struggle of the Patriotic Filipino Masses) was the umbrella political coalition party of the opposition during the 1998 Philippine Presidential Elections that led to the presidency of then Vice President Joseph Estrada. It was the largest political party of that time, uniting the major parties of Senator Edgardo Angara (LDP-Aurora)'s Laban ng Demokratikong Pilipino (Struggle of Democratic Filipinos), tycoon Eduardo Cojuangco Jr.'s Nationalist People's Coalition, Vice President Joseph Estrada's Partido ng Masang Pilipino (Party of the Filipino Masses) and Aquilino Pimentel Jr.'s Partido Demokratiko Pilipino-Lakas ng Bayan along with minor and regional parties. Estrada's running mate, Senator Edgardo Angara lost to Senator Gloria Macapagal-Arroyo (LAKAS-Pampanga). Joseph Estrada won against runner-up then House Speaker Jose de Venecia (LAKAS-Pangasinan) with 3.1 million plurality. After the 1998 elections, the party name was changed into Lapian ng Masang Pilipino (LAMP, English: Organization of the Filipino Masses), as the "struggle" ended with victory of Estrada.
