Sinas is a surname used by individuals of Filipino origin, though it has also appeared in diaspora communities around the world. It is most commonly encountered as a family name in the Philippines.

The etymology of Sinas is not well documented in standard onomastic references. As with many surnames in the region, its origin may reflect a mix of historical influences and local naming practices rather than a single clear lineage. The distribution of the name is concentrated in the Philippines, with established communities abroad in North America, Europe, and other regions through migration.

In contemporary contexts, people with the surname Sinas have appeared in public life, academia, business, and sports, though no single individual is universally identified as defining the name. The surname is considered relatively uncommon in global terms.
