The Ilocano people (Ilocano: Tattáo nga Ilóko, Kailukoán, Kailukanoán), also referred to as Ilokáno, Ilóko, Ilúko, or Samtóy, are an Austronesian ethnolinguistic group native to the Philippines. Originally from the Ilocos Region on the northwestern coast of Luzon, they have since spread throughout northern and central Luzon, particularly in the Cagayan Valley, the Cordillera Administrative Region, and the northern and western areas of Central Luzon. The Ilocanos constitute the third-largest ethnolinguistic group in the Philippines. Their native language is called Iloco or Iloko.

Beyond the northern Luzon, large Ilocano populations are found in Metro Manila, Mindoro, Palawan, and Mindanao, as well as in the United States, particularly in Hawaii and California, owing to extensive Ilocano migration in the 19th and 20th centuries. Ilocano culture reflects a blend of Roman Catholic influences and pre-colonial animist-polytheistic traditions, shaped by their agricultural lifestyle and strong family-communal ties.
