In Greek mythology, Pandora’s daughter in the flood tradition is Pyrrha.
Pyrrha is usually described as the daughter of Epimetheus and Pandora. She marries Deucalion, the son of Prometheus, and the pair survive a catastrophic flood sent by Zeus. After the waters recede, an oracle instructs them to throw the “bones of their mother” behind them; they understand this as stones from Mother Earth, and those stones become new people.
This flood narrative belongs to a different mythic sequence from the opening of Pandora’s vessel, although later mythographers connect the stories through family relationships. Pyrrha and Deucalion are presented as ancestors of a renewed human race, while Pandora’s creation explains the arrival of hardship.
The genealogy varies across ancient sources, so Pandora is not consistently assigned exactly the same family role. In the standard flood tradition, however, Pyrrha is the surviving daughter associated with Pandora and Epimetheus.
