Danno is English in Origin.

Danno is an informal Anglophone pet form of Daniel, especially in Ireland and other English-speaking regions, built with the breezy -o nickname suffix found in Irish and Australian usage (compare Robbo or Jacko). As a derivative of Daniel, it ultimately comes from the Hebrew Daniyyel, combining dan “judge” and el “God,” yielding the meaning “God is my judge.” While primarily a nickname, Danno is occasionally adopted as a standalone given name in modern records.

The name gained wider recognition in the mid-20th century: Irish wrestling champion Danno O’Mahony bore the nickname, and television further popularized it through Hawaii Five-O’s catchphrase “Book ’em, Danno,” for Detective Danny (Daniel) Williams. Related forms include Daniel, Dan, Danny, and the Slovak Dano; international variants include Danilo, Danial, and the feminine Danielle, Daniela, and Daniella. Danno conveys a friendly, informal tone while retaining the time-tested roots of Daniel.
