Classic and elegant but with boyish charm, Theodore has become hit name in recent years, vaulting into the US Top 10 in 2021 for the first time ever and into the Top 5 in 2024. A favorite in English speaking countries, it also ranks highly across the UK and Ireland, and in Canada, New Zealand, and Australia. 

Friendly nickname Theo may be responsible for some of that, though there are plenty of baby boys given Theo as their full name too. Add their numbers together along with those for Mateo and Teo, and they hands-down become the Number 1 boys' name.

Theodore and Mateo are far from interchangeable names, for sure, and some Theodores are called Teddy....or Theodore. But we predict an overwhelming number of little boys called Theo or Teo on American playgrounds over the coming years.

Theodore is a derivative of the Latin Theodorus, a variation of the Greek name Theodōros. The components are from the Greek words theos, meaning "God," and dōron, meaning "gift," giving Theodore the meaning "God-given" or "gift of God." Names with similar origins include Theodora, Dorothy, and Dorothea.
 
When Theodore Roosevelt took office in 1901, the name Theodore was in the Top 40 <a href="https://nameberry.com/boys-names">boy names</a>, with Teds and Teddys everywhere. After some damaging stereotypes—the chubby Chipmunk Theodore and Beaver Cleaver's real name—Theodore went into a decline, from which it has definitely made a recovery, thanks in part to the popular and likable nickname Theo.
 Theodore has been the choice of several celebrities, including Ivanka Trump, Bryce Dallas Howard, Natascha McElhone, and Ali Larter, not to mention being the fictional son of Christian and Ana in Fifty Shades of Grey.
 The name has a distinguished history. In addition to being presidential, it was borne by novelist Dreiser, poet Roethke, and French painter Gericault, and it was the first name (spelled Theodor) of Dr. Seuss.
 Among the well-known Teds, baseball's Williams and musician Nugent were born Theodore, but Ted Turner was christened Robert, and Ted Kennedy and Ted Danson were originally Edward.
 The beloved character Laurie in Little Women was named Theodore Laurence.
