Iba, Zambales is a first-class municipality and the capital of Zambales. Situated on the western coast of Luzon, Iba serves as an administrative, cultural, and service center for the province and surrounding municipalities such as Olongapo, Castillejos, San Antonio, and Botolan. The town is noted for its coastal geography along the South China Sea, historical ties to Spanish colonial administration, and local festivals that attract visitors from Manila and neighboring provinces like Pampanga and Bataan.

History

Iba's documented history begins during the Spanish colonial era when Augustinian missionaries linked the settlement to wider developments involving Manila, Vigan, and the colonial Philippine Islands. The town served as an ecclesiastical center connected to parishes administered by the Order of Saint Augustine and later saw administrative reforms under the Spanish East Indies and measures tied to the Cadiz Constitution. During the Philippine Revolution and the Philippine–American War, nearby sites in Zambales experienced clashes involving units from the Philippine Revolution and American forces, while national events such as the Treaty of Paris (1898) and the establishment of the Commonwealth of the Philippines affected provincial administration. In the 20th century, Iba witnessed infrastructure expansion aligned with projects promoted under the United States in the Philippines period and later became consolidating center with ties to the Republic of the Philippines after independence. Natural disasters including eruptions from Mount Pinatubo and typhoons have reshaped local development in the late 20th century, intersecting with relief efforts by organizations like the Philippine Red Cross and initiatives from the Department of Social Welfare and Development.
