The Cry of Pugad Lawin (Filipino: Sigaw sa Pugad Lawin, Spanish: Grito de Pugad Lawin) was the beginning of the Philippine Revolution against the Spanish Empire.
In late August 1896, members of the Katipunan led by Andrés Bonifacio revolted somewhere around Caloocan, which included parts of present-day Quezon City.
Originally the term cry referred to the first clash between the Katipuneros and the Civil Guards (Guardia Civil). The cry could also refer to the tearing up of community tax certificates (cédulas personales) in defiance of their allegiance to Spain. This was literally accompanied by patriotic shouts.
Because accounts of the event vary, the exact date and place of the event is unknown. From 1908 until 1963, the event was thought to have occurred on August 26 in Balintawak.
