Beelshamên, or Baal-Shamin (Syrian Semitic), was a supreme deity and the sky god of pre-Islamic Palmyra in ancient Syria. His attributes are the eagle and the lightning bolt. "Beel" is also equivalent to the semitic Baal and Bel, meaning "Lord", and was an ancient name for Enlil and Marduk.

Beelshamên formed a triad with the lunar god Aglibol and the sun god Malakbel (or Yarhibol).
