Origin: Hebrew

Meaning: messenger of God

Malachi is a masculine name of Hebrew origin, meaning "messenger of God." It is a biblical name associated with the religious prophet and author of the Book of Malachi in the Old Testament. Malachi is also a variant of Malachy and shares its name with the first Irishman to be canonized in the Roman Catholic Church. While its origins are religious, Malachi offers plenty of appeal to secular families too. By shortening it to Mal or Kai, you can reinvent this classic and present baby Malachi with a sweet nickname.
