Illinois’s 2025 popular baby names are led by Olivia and Liam, with Charlotte and Noah close behind.
On the girls’ side, Olivia’s 501 babies put her just ahead of Charlotte’s 500, a remarkably tight race at the top. Sophia and Emma follow closely, while Mia slips three spots and Camila climbs two, giving the leaders a mix of steady favorites and small shifts.
Liam tops the boys’ list with 690 babies, ahead of Noah’s 683, while Oliver and Theodore keep the next spots close. The biggest mover is Leo, up ten places, and Sebastian adds three; Mateo and Benjamin each slip one.
Style-wise, the girls’ list favors soft, vowel-rich classics and polished, vowel-forward choices, while the boys’ side runs on sturdy traditional names with a few short, lively picks like Leo breaking through. Henry, James, Amelia, Evelyn and Isabella keep the old-favorite thread strong across both lists.
