Popular Dominican Last Names

Dominicans are predominantly Spanish speakers, with a few English-speaking people. Its culture is an eclectic mix of cultural influences from Spaniard colonists, African slaves, and Taíno natives. 

Dominican naming customs are distinguished primarily by the vocalization of liquid consonants, different spellings, and rhotacization, which affects pronunciation and results in more atypical spellings.

Surnames are inspired by:

  • The Spanish language
  • History
  • The Bible
  • Some American surnames 
  • Fusing two names to form a compound, such as manipulating both parents’ names.

Surnames have spread far beyond their country of origin due to globalization. It is possible to find African surnames in the Americas or Indian names in Europe. As a result, the majority of Dominican surnames may be found in various nations around the world. This is due, in great part, to the widespread influence of Spanish culture on territories and colonies throughout the Americas, Asia, and Africa.
