Meaning & origin
Millie has enjoyed a notable resurgence in the United States, rising to a rank of 73 in 2025, with approximately 1 in 479 newborn girls receiving the name. This marks a significant climb from a low point in the mid-20th century; the name has been on an upward trajectory since 1991. Its peak year is 2025, indicating continued momentum. Millie is particularly favored in states like Wyoming, Montana, and North Dakota, reflecting a broader trend toward vintage, friendly-sounding names. While originally a diminutive for Millicent, Millie has long functioned as an independent given name, embodying a blend of old-fashioned charm and modern simplicity.
Millie originated as a pet form of Millicent, which itself comes from the Old French name Melisende, likely of Germanic origin meaning 'strength' and 'battle'. It has been used independently since the 19th century, gaining particular popularity in the late Victorian era and again in the 2020s. The name has been associated with a sweet, friendly image.
