Portuguese female names come from the Portuguese language in Portugal and Brazil. Most use feminine endings such as -a and -ina, with productive diminutives in -inha. Many have explicit feminine forms that parallel masculine counterparts (for example, Cristiana). Compound names are longstanding, especially with Ana or Maria as the first element, and diacritics often appear in formal spellings.

Current usage favors traditional compounds and mainstream modern forms, while some Brazilian records also include variant spellings. Diminutives and short forms sometimes appear as given names. Common examples include Ana, Ana Sofia, Ana-Maria, Camila, Carolina, Catarina, Bruna, Andressa, Cristiana, and Daiane.
