|   Latin Iustinius or Iustinus | 
Justin is an anglicized form of the Latin given name Justinus, a derivative of Justus. Justinus was the name borne by various early saints, notably a 2nd-century Christian apologist and a boy martyr of the 3rd century (possibly spurious). As an English name, Justin is common particularly in the English-speaking world starting in the latter half of the 20th century.
