In Greek mythology, the name Eurythemista /jʊərɪθɪˈmɪstə/^{[citation needed]} or Eurythemiste /-ˈmɪstiː/ (Ancient Greek: Εὐρυθεμίστη) may refer to:

• Eurythemista, a Calydonian princess as the daughter of King Porthaon and Laothoe.^[1] She was the sister of Sterope and Stratonice, wife of King Melaneus of Oechalia.
• Eurythemista, daughter of the river-god Xanthus, thus can be considered a naiad nymph. She is one of Pelops' and Niobe's possible mothers by Tantalus^[2] (other ones being Euryanassa and Dione, daughter of Atlas).
• Eurythemista, one of the two maidens that were wooed by Boeotus. He could not choose between the two until he saw a star fall on Eurythemiste's shoulder; he then took her to wife.^[3]
