Teagan
TEE-gan
Teagan derives from the Irish surname Ó Tadhgáin, connected to the Gaelic word tadhg meaning “poet” or “philosopher.” The transition from surname to given name followed the familiar American pattern of adopting Celtic surnames as first names.
The name’s US trajectory shows a classic rise-and-fall arc. Teagan peaked at No. 150 in 2016, having climbed from relative obscurity in the early 2000s. At its height, over 2000 girls received the name annually.
By 2024, the descent was well underway: Teagan ranked No. 333 with 936 births, roughly half its peak-year volume. The decline has been steady, losing about 20-30 positions per year since 2020.
What the name Teagan means
The name’s sonic similarity to Reagan, Megan, and Keegan placed it in a crowded phonetic neighborhood. As that entire cluster has cooled, Teagan has followed the group trend downward.
Despite the numbers, Teagan retains genuine strengths. Its Irish roots give it cultural depth, the meaning (“poet”) is appealing, and the 2-syllable structure keeps it crisp and efficient.
For parents who value Celtic heritage without reaching for the most common Irish choices like Aiden or Riley, Teagan offers a solid middle ground.
Its retreat from peak popularity actually makes it a more distinctive choice today than it was a decade ago.
