Juliana (variants Julianna, Giuliana, Iuliana, Julijana, Yuliana, Uljana, Xuliana or Xhuliana, etc.; in English Jillian, Gillian) is a feminine given name. It is the feminine form of the Roman cognomen Julianus, which gave rise to the masculine given name Julian. Julian was the name of a number of early saints, notably Saint Julian the Hospitaller, which went to ensure the name's continued popularity in the medieval period.
