Who is the Taoist goddess of childbirth and dawn?

The Taoist goddess of childbirth and dawn is Bixia Yuanjun.

Also known as Taishan Niangniang, Bixia Yuanjun is closely associated with Mount Tai in Shandong Province. As a goddess of childbirth, she was believed to hear prayers from people seeking children and to influence a child’s destiny. Her dawn aspect connects her with the arrival of each new day, symbolized by her residence among the clouds.

Her worship became especially prominent in northern China during the Ming and Qing periods. Pilgrims visited the Palace of the Clouds of Dawn at Mount Tai, where women prayed for fertility and safe childbirth. She was also linked with longevity, fate, and the judgment of the dead, giving her a wider religious role than the question’s short description suggests.

Bixia Yuanjun is sometimes confused with Xiwangmu, the Queen Mother of the West, or with Guanyin, whose popular worship also included appeals for children. Those figures have overlapping associations, but Bixia Yuanjun is the deity specifically identified with Mount Tai, childbirth, and dawn.
