Three baronetcies have been created in the Baronetage of England for members of the Littleton or Lyttelton family. All three lines are descended from Thomas de Littleton, a noted 15th-century jurist. Despite differences in spelling of the title, the names of all three lines were spelt in many varied ways in the early modern period, without distinction between the different branches of the family. This can be confusing, as the range of forenames in use was very limited.
