Very popular at the turn of the 2000s, it today retains a special place in rankings. With its simple and bright sound, this first name of Greek origin continues to seduce young parents in France as abroad.
A story marked by the Greek tradition
From the Greek word theoswhich means “God”, the first name Théo has long been used as a diminutive of longer first names such as Théodore, Théophane or Thétime. These names carrying a strong Christian tradition began to spread in Europe from the 16th century.
But it was truly in the late 1980s that this short first name made a remarkable entry into French maternities. Carried by the fashion of brief first names, he quickly won and quickly exceeds his elder Théodore. In the early 2000s, he even reached 2ᵉ place for the most attributed male first names, just behind Thomas.
Still in the top 50 in France
In 2025, around 132,000 people took this first name in France, according to The official first names (First Éditions). Despite a slight decrease compared to its peak, it still appears in the national top 50 and remains particularly acclaimed in certain regions, such as the Dordogne, where it joined the departmental top 10 this year.
Internationally, he retained a certain influence: he ranked 13ᵉ in Quebec in 2023, 16ᵉ in French -speaking Switzerland in 2022 and even 8ᵉ in Wallonia the same year.
Variants and first names in “O”: a lasting trend
The Téo variant, also from the Greek, seduces around 10,000 French people in 2025. Rarely, it remains in the top 400 male first names, but enjoys a good popularity in Italy and in Hispanophone countries.
More broadly, the “O” endings continue to have the odds. While Théo and Hugo decline slightly, Léo remains essential. Other first names like Elio, Nino, Milo or Pablo gain ground, reflecting the growing attraction for Italian and Mediterranean sounds.
Portrait and associated character
According to characterology, the bearers of this first name are distinguished by their sense of communication, their optimism and their creativity. They are often pragmatic and attentive to others. The TEO variant, on the other hand, evokes rather efficiency, perseverance and righteousness.
This male first name, which is celebrated on November 9, therefore continues to embody a successful alliance between tradition and modernity, carried by the force of its simplicity.
