Delylah is a modern spelling of Delilah, the Hebrew name of the woman who betrayed Samson; its meaning is uncertain and is usually given as "delicate" or "languishing". The biblical story kept the name out of use for centuries, but its lilting sound made Delilah a 21st century favorite, and spellings like Delylah followed. In the United States Delylah ranked number 11000 in 2000, peaked at number 1951 in 2020 and stood at number 2619 in 2025 with 66 girls.
