Which Titan was Pandora’s brother-in-law in the myth of Pandora’s jar?

Prometheus was Pandora’s brother-in-law in the myth of Pandora’s jar.

Prometheus was the brother of Epimetheus, Pandora’s husband. That family connection places him directly inside the story even though he is not Pandora’s spouse. Prometheus is best known for stealing fire from the gods and giving it to humanity, an act that provoked Zeus’s punishment.

After the theft, Zeus arranged Pandora’s creation as part of the punishment directed at humans and at Prometheus’s wider circle. Prometheus reportedly warned Epimetheus not to accept gifts from Zeus, but Epimetheus accepted Pandora anyway. This sequence helps explain why Prometheus and Pandora are frequently mentioned together.

A common mistake is to call Prometheus Pandora’s husband. In the myth’s family structure, he is her brother-in-law. Prometheus’s name is associated with forethought, while Epimetheus’s name is associated with afterthought, reinforcing the contrast between warning and belated understanding.
