The Romblomanon people are the indigenous inhabitants of Romblon province. They are part of the wider Visayan ethnolinguistic group, who constitute the largest Filipino ethnolinguistic group.
Romblomanons live mainly in the province of Romblon. However, due to population increase, which the island province's small area couldn't sustain, there are also significant numbers of Romblomanons in Occidental Mindoro and Oriental Mindoro, Masbate, Aklan, Palawan and probably parts of Mindanao.
Romblomanons number about 24,856, and are considered as Visayans. Romblomanons speak one of three languages, the Romblomanon language, Asi language, and the Onhan language. Most are Roman Catholics.
