Sire

Historically, Sire was a formal term for addressing male royalty, particularly a king. Sire can also mean "father" or "senior" as both a noun and a verb. Now, like Prince, Sir, Messiah, and Saint, this title is now a name on the rise.

Rarely given as a name until the mid-2010s, Sire is now chosen for over 100 baby boys each year. It fits in alongside Duke and King and of course, Royal itself, while also sharing the sounds of more established choices like Silas or Ira.

Musician Usher and Jenn Goicoechea named their son, born in October 2021, Sire Castrello, which likely introduced it as a possibility to a wider audience.

Pronounced SY-ur.

As of October 2026, Sire ranked #1475 in US births in 2025 SSA, peaked at #1229 in 2020.
