About Theo
Most commonly used as a short form of Theodora or Theodosia, this "boyish" nickname for girls is used much less frequently than Thea, Dora, or Teddy. One notable appearance however, was as the younger daughter in Sofia Coppola's film On the Rocks in 2020, while antiques expert, Theo Burrell was a real life bearer.
Given to 21 girls compared to more than 3900 boys in the US in a recent year, you may be surprised to learn that Theo was a Top 1000 name for girls from 1880 until 1930, and while some of this may have been down to errors in record keeping, this is unlikely to explain the 111 girls called Theo in 1924 or the 109 girls given the name in 1919.
With Scottie, Bennie, Stevie, and Davey on the rise for girls, alongside Margo, Cleo, Juno, and Theodora, perhaps you may hear of more girls called Theo in the future.
Pronounced THEE-oh.
As of October 2026, Theo ranked #5894 in US births in 2025 SSA, peaked at #522 in 1887.
