Luna is the Latin word for the moon, and name dictionaries agree that the name is a direct use of that noun. In Roman religion, Luna was the goddess of the moon, usually identified with the Greek Selene. The word is also the ordinary Spanish and Italian term for the moon, so the meaning stays transparent to speakers of those languages.
It is pronounced LOO-nuh, with a long first vowel and an unstressed second syllable. American and British English pronounce it the same way.
The oldest and best-known association is the Roman moon goddess. In modern culture the name is closely tied to Luna Lovegood, the character in J. K. Rowling's Harry Potter series. Among living namesakes, the South Korean singer Luna, born Park Sun-young, is familiar to K-pop audiences.
In the United States, Luna was given to 6,076 girls in 2025 and ranked 27th. Its rise has been rapid: in 2000 it stood at 1,318th, and it entered the top 100 in 2016. It reached its peak of 10th in 2022 and 2023, when 8,977 girls received the name, and it has eased slightly since then while remaining among the most common names for girls.
