Tiago

Tiago, also spelled Thiago, is a popular Portuguese boys' name. Derived from the more formal Santiago, these days it is often used on its own. Relaxed and charming while still maintaining the sophistication of its long form, Tiago is popular in its native Portugal, but also in France, Belgium, Brazil, and the UK.

English speakers may not intuitively get the Latin American pronunciation (chee-AH-go) and might say it as a blend of that, and the European Portuguese form (tee-A-goo), making it into tee-AH-go.

A creative way to honor an ancestral James or Diego, or an alternative to the now very popular Mateo, Tiago was given to more than 200 boys in a recent year, while Thiago was given to 4500, meaning this name will inevitably sound more popular than it actually is.

Pronounced tee-AH-go.

As of October 2026, Tiago ranked #1117 in US births in 2025 SSA, peaked at #1027 in 2022, Nameberry popularity #655.
