Rabel II Soter (ar-Rabil) was the last ruler of the kingdom of the Nabataea, ruling from AD 70 to 106.
After the death of his father, Malichus II, ar-Rabil still a child, ascended to the throne. His mother, Shaqilath, assumed control of the government in the early years. His sister Gamilath became queen of the Nabateans. Ar-Rabil gave himself the title "Soter" ("Savior of the People"). After his death in 106, the Roman emperor Trajan faced practically no resistance and conquered the Nabataean kingdom on 22 March 106. It became the Roman province of Arabia Petraea, with Bosra becoming its provincial capital.
Ar-Rabil's formal successor was Malichus III.
