What is the name of Korra's father?

Tonraq is the name of Korra’s father. He is the chief of the Southern Water Tribe and the husband of Senna, Korra’s mother.

Tonraq was originally heir to the leadership of both Water Tribes and served as a general in the Northern Water Tribe. His career changed after he destroyed a sacred spirit forest while pursuing criminals. His younger brother, Unalaq, used the incident to engineer Tonraq’s banishment and inherit political influence in the North.

After moving south, Tonraq became the Southern Water Tribe’s unofficial leader and raised Korra with Senna. When Unalaq’s plans triggered conflict between the tribes, Tonraq led the Southern rebels against him. Following Unalaq’s death, Tonraq was formally appointed the first chief of an independent Southern Water Tribe. Tarrlok and Yakone are associated with Republic City’s criminal and political history, while Unalaq is Korra’s uncle.
