Cojuangco is the Hispanised Filipino-Chinese surname Kho ( Hanzi: 許, pronounced in Hokkien and Xu ([s̪u˧ˀ˦]) in Mandarin). The Cojuangco clan is among the most powerful and influential in the Philippines, exercising economic control over several banks (such as Bank of Commerce) and trade houses, partly due to marriages with the Ayala and Roxas families and partly to their own business enterprises (notably the sugar trade). The clan has at various time been highly involved in Philippine politics, with several members having entered public office in both local and national positions.
The clan is descended from Co Yu Hwan (; Quanzhou Hokkien literary: Hěu Ggiókhuán; colloquial: Koǒ Ggiákkuán), who migrated from Hongjian Village, Jiaomei Township, Zhangzhou, Fujian to the Spanish East Indies in 1861. He was commonly called Kuán Goō ( "Brother Kuan") or Koǒ Kuán Goō ( "Brother Koo Kuan") among Hoklo- Filipinos, and the latter was hispanicised as Cojuangco. He adopted the Christian name José in 1865, when he moved to Bulacan.
