Adalia is usually linked to the Germanic adal, meaning "noble", as in Adeline and Adelaide, though the name also appears in the Book of Esther as a Persian name of unknown meaning. In the United States it is often chosen as a fresher take on Adalyn and Dalia. Adalia has grown slowly but steadily, from number 4080 in 2000 to number 1579 in 2024, and ranks number 1721 in 2025.
