The Kapampangans or Pampangos or are the sixth largest Filipino ethnolinguistic group, numbering about 2,890,000. The original Kapampangans may have descended from Austronesian-speaking immigrants to Luzon during the Iron Age.

The province of Pampanga is traditional homeland of the Kapampangans. Once occupying a vast stretch of land that extended from Tondo to the rest of Central Luzon, huge chunks of territories were carved out of Pampanga so as to create the provinces of Bulacan, Bataan, Nueva Ecija, Aurora and Tarlac. As a result, Kapampangans now populate a region that extends beyond the political boundaries of the small province of Pampanga. In the province of Tarlac, the indigenous population of Tarlac City and the municipalities of Bamban, Capas and Concepcion are Kapampangans, while the municipalities of Victoria, La Paz, have a significant Kapampangan population. In Bataan, Kapampangans populate the municipalities of Dinalupihan and Hermosa, and the barangays of Mabatang in Abucay and Calaguiman in Samal. Kapampangans can be found scattered all across the southern barrios of Cabiao in the province of Nueva Ecija and in the western section of the province of Bulacan. Kapampangan enclaves still exist in Tondo and other parts of the National Capital Region. Kapampangans have also migrated to Mindoro, Palawan and Mindanao and have formed strong Kapampangan organizations called aguman in Davao City and General Santos City. Agumans based in the United States and Canada are active in the revival of the Kapampangan language and culture.^{[citation needed]}
