Bahias

Bahias is a term that can refer to multiple bays, as the plural form of the Spanish word bahía, or to its use in place names and descriptive contexts within Spanish- and Portuguese-speaking regions. In geography, a bahía (bay) is a coastal inlet partially surrounded by land, with a wide opening to the sea that provides sheltered waters. The plural bahias is used when discussing more than one bay. In Portuguese, the equivalent word is baía, with the plural baías.

In toponymy, bays are frequently incorporated into names, such as Bahía de [X] or Baía de [X], reflecting the local geography rather than a fixed, standalone entity called “Bahias.” The form and spelling vary by language and country, with usage typically aligning to the local orthography (bahía in Spanish, baía in Portuguese). The plural Bahias itself is rarely used as an independent geographic name and is more commonly encountered in descriptive or list-based references.

As a surname, Bahias can be found in some Spanish- and Portuguese-speaking communities, though it is relatively uncommon and does not denote a widely recognized historical family or figure in most sources.
