The Reform the Armed Forces Movement, also referred to by the acronym RAM, was a cabal of officers of the Armed Forces of the Philippines (AFP) known for several attempts to seize power in the Philippines during the 1980s and 1990s. In 1986, some of these officers launched a failed coup d'etat against Ferdinand Marcos, prompting a large number of civilians to attempt to prevent Marcos from wiping the RAM rebels out. This eventually snowballed into the 1986 People Power revolution which ended the dictatorship of Ferdinand Marcos and forced him into exile. RAM later attempted six coups d'tat against the administration of Corazon Aquino.

The most serious attempted coup d'état against the government of Philippine President Corazon Aquino was staged beginning December 1, 1989, by members of the Armed Forces of the Philippines belonging to the Reform the Armed Forces Movement (RAM) and soldiers loyal to former President Ferdinand Marcos. Metro Manila was shaken by this Christmas-time coup, which almost seized the Malacañang Palace. It was completely defeated by the Philippine government by December 9, 1989.
