Neythan is a modern spelling of Nathan, a Hebrew name that means "he gave" or "gift" and belongs to the prophet who confronted King David. The ey spelling is mostly used in Spanish-speaking families, where it reflects the English pronunciation, in the same way as Izan for Ethan. Neythan had fewer than five births in 2000, climbed from number 4370 in 2015 to number 1112 in 2024 and entered the top 1000 for the first time in 2025 at number 926.
