Mateo is the Spanish form of Matthew, a name that derives from the Hebrew Mattityahu, commonly translated as gift of God or gift of Yahweh. Name dictionaries agree on this origin, and the same Hebrew source stands behind the Italian Matteo and the English Matthew. Mateo has been used in Spanish-speaking countries since the medieval period and remains a common given name there.
In Spanish it is pronounced mah-TAY-oh, with the stress on the middle syllable and a clear final vowel. The same pronunciation is usual in American and British English.
Among the best-known bearers are Mateo Alemán, the sixteenth-century Spanish novelist who wrote Guzmán de Alfarache, and Mateo Kovačić, the Croatian midfielder who has played for Manchester City and the Croatia national team.
Mateo's rise in the United States has been steep. In 1995 it was given to 125 boys and ranked 994th.

In 2025 it was given to 11,045 boys and ranked 8th, placing it firmly among the country's ten most popular boys' names.
