Rabel II Soter (ar-Rabil) is the last ruler of the kingdom of the Nabataeans, ruling from CE 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 gives himself the title "Soter" ("Savior of the People").

After his death in 106, the Roman emperor Trajan faces practically no resistance and conquers the Nabataean kingdom on March 22, 106.

It becomes the Roman province of Arabia Petraea, with Bosra becoming its provincial capital.

Ar-Rabil's formal successor is Malichus III.
