In Greek mythology, Larissa or Larisa (Ancient Greek: Λάρισα, romanized: Lárisa) is the daughter of Piasus, a Thessalian or Anatolian king who was desired by her father and eventually was raped by him while still a maiden. Later in her life, Larissa became the wife of Cyzicus, a different Anatolian king.

The noun Λάρισα in ancient Greek meant a citadel or a fortress, and was derived from a pre-Greek substrate.^[1]

Larissa was the daughter of Piasus, king of the Pelasgians,^[2] though also called Piasus the Thessalian,^[3] by an unnamed mother. Her father was also said to have been honoured in Larissa Phrikonis, a Pelasgian settlement in Aeolis, an ancient region on the western coast of Asia Minor.^[4][5]

The young Larissa is said to have caught the eye of her father Piasus who developed a passion for her, and in his ‘unfortunate’ desire he proceeded to rape the unwilling Larissa.^[6][3] According to Strabo, Larissa would have her revenge when one day she observed her father leaning over a cask of wine, drinking. She quickly seized him by the legs and plunged him into the cask, causing his death by drowning.^[4][7]

Some unspecified time after her violation by her father, Larissa became the wife of Cyzicus, the ruler of the Dolonians (a tribe dwelling on the southern shore of the Propontis sea).^[8]
