In Greek mythology, Side (Ancient Greek: Σίδη, romanized: Sídē, lit. 'pomegranate'^[1]) or Sida was the name of the following figures:

• Sida, eponym of the city of Sidon in Phoenicia. She was the wife of Belus, king of Egypt and mother of Aegyptus and Danaus.^[2] Otherwise, the wife of Belus was called Achiroe, daughter of the river-god Nilus.^[3]
• Side, one of the Danaïdes, condemned to Tartarus for murdering her husband. From her, a town in Laconia was believed to derived its name from.^[4]
• Side, the first wife of Orion and possible mother of his daughters Metioche and Menippe.^[5] She was cast by Hera into Hades because she rivaled the goddess in beauty.^[1] Modern scholars interpret the supposed marriage of Orion to Side ('pomegranate') as a mythical expression for the ripening of the fruit in the season when the constellation Orion is visible in the night sky.^[1]
• Side, a mortal woman who was chased down by her father Ictinus, intending to rape her. Side killed herself on her mother's grave, and the gods turned her blood into a pomegranate tree. Her father was changed into a kite bird that never rested on pomegranate trees.^[6]
