Aglaurus (/əˈɡlɔːrəs/; Ancient Greek: Ἄγλαυρος) or Agraulus (/əˈɡrɔːləs/; Ancient Greek: Ἄγραυλος) is a name attributed to three figures in Greek mythology.^[1]

• Aglaurus, the daughter of Actaeus, the first king of Attica. She married Cecrops and according to Apollodorus became the mother of Erysichthon, Agraulus, Herse, and Pandrosus;^[2] other authors, however, including Pausanias and Hyginus, state that the eldest daughter of the couple is "Aglaurus" (see next entry), not "Agraulus".^[3]
• Aglaurus, the daughter of Cecrops and the above Aglaurus, who was driven to suicide for ignoring a warning from the goddess Athena.^[4]
• Aglaurus, daughter of an incestuous relationship between Erectheus and his daughter Procris.^[5] Aglaurus is also known as Aglauros (most commonly), Aglaulos, Agraulus, Agravlos, or Agraulos. Agraulos ("countryside flute") was probably the original form of the name, with the r and l commonly switched to produce the prevalent Aglauros form.
