Portuguese Names that Start With O

Ovidia is the unusual feminine form of the ancient Roman Ovidius, most famous as the name of the exiled 1st century Roman poet Ovid. Modern male form Ovidio is known in Spain and Portugal. Ovida is another variation.

Othão is a masculine name with Portuguese origins, likely a variant or elaborate form of Otto or Otho. These names derive from Germanic roots meaning 'wealth' or 'prosperity.' The tilde over the 'a' (ã) creates a nasal sound distinctive to Portuguese pronunciation. Othão remains quite rare even in Portuguese-speaking countries, making it an exceptionally distinctive choice. The name carries an aristocratic, historical resonance while the Portuguese pronunciation gives it a flowing, melodic quality. Othão might appeal to families with Portuguese heritage or those seeking a name with European flair that remains highly uncommon. Despite its rarity, the name connects to the more familiar Otto, providing some historical grounding.

Olivieros is a masculine name with Greek and Latin origins, serving as an elaborate form of Oliver. Deriving from the Latin 'olivarius' meaning 'olive tree planter,' it carries connotations of peace and fertility, as olive branches symbolize peace in many traditions. This ornate variation adds a distinctly Mediterranean or Spanish flair to the more common Oliver. While rare in most English-speaking countries, Olivieros might be found occasionally in Greek, Spanish, or Portuguese-speaking regions. The name has a melodious, romantic quality with its flowing syllables and classical roots, making it an uncommon but meaningful choice for parents seeking a name with historical depth and distinctive character.

Olivia ranks in the Top 10 -- and sometimes even Number 1 -- in many countries now, so variations such as this Spanish form may get some attention.
