Rey peaked in 2021 and holds rank #821 with 9,431 SSA records. Three letters, one syllable, and two separate cultural forces pushing it: the Spanish word for king, and the Star Wars protagonist who made the spelling a household name starting in 2015. It's a small name carrying a lot.
Spanish Royal Roots
Rey means "king" in Spanish — direct, unambiguous, and regal. The Spanish origin places it in the tradition of meaning-forward Latino naming: parents who choose Rey for their son are choosing a word that means something immediately legible to a huge portion of the American population. It's related to the Latin rex and connects to royal names across the Romance language tradition — Roy, Rex, Leroy, Roy all share this etymological lineage in different forms.
The Star Wars Effect
When The Force Awakens opened in December 2015, the character Rey — played by Daisy Ridley — gave this spelling massive pop culture visibility. The SSA data for Rey as a boys' name continued climbing through that period, though Rey the character is female. For boys, the name tracks the broader trend of short, punchy names with royal meaning, alongside names like Reign and Rex. See how Rey compares to those alternatives at Rey vs. Rex.
Counter-Reading
Three-letter, one-syllable names for boys carry an interesting challenge: they feel bold and decisive, but they can also read as abbreviated rather than complete. Some people will assume Rey is a nickname for Reynaldo, Raymond, or Reyes. The Star Wars association also creates some gender ambiguity , at least for the next decade while the films remain fresh. If you want a short, strong Spanish name with absolute clarity, Rex has less cultural noise, though considerably less warmth. Check the full rankings to see where Rey sits.
