盤古公即盤古，又稱盤古聖帝、盤古聖祖等，是中國神話裡開天闢地的人物。盤古最早的神話記載於三國時期吳國徐整所著《三五歷記》，故事描述古代的創世觀，古人認為天地未開之時宛如雞蛋一片混沌，人類祖先盤古誔生其間。經過一萬八千年天地開始分離，期間盤古每長高一丈，天地就分開一丈。盤古作為天地初開第一人，死後氣息化成風雲，聲音變成雷聲，眼睛成為日月，四肢和身體成大地和山，血液成為河川，肌肉化土壤，身上種種皆成宇宙萬物，身內的各種蟲，被風吹襲後成為人類。此為盤古開天闢地神話。
盤古的傳說後來被道教吸納，名叫盤古真人，也就是道教的神仙，又作元始天尊，元始天王。根據葛洪的《枕中書》，天地未分前，由天地精華育孕的盤古已在其中，且自號元始天王。天地始開後，他遇到聖女太元，喜愛其貞潔，化作青光入其口中，使之受孕，十二年後盤古從太元的背脊出生，出生後有彩雲護身的瑞相。在陶弘景《真靈位業圖》裡，眾神仙要按時朝覲元始天尊，號「玉清紫虛高上元皇太上大道君」。《述異記》裡還指出，盤古的墓地在南海。
自古即有主祀盤古的廟宇，四川稱盤古祠或盤古三郎廟。《歲時習俗資料彙編》載古以十月十六日為盤古誔辰，湖南湖北一帶認為因為盤古誔生即開天闢地之時，節氣正巧是陰陽始分之日。臺灣民間廟宇中，主祀盤古者不多，視主祀元始天尊等同主祀盤古，例如新店開天宮、新竹五指山盤古廟、開天宮、臺南玉井的大王宮和盤古殿，還有新化的盤古王廟等。

When the heaven and the earth begin to separate, Pangu is born and grew up at the same time. Finally, Pangu is as high as the distance between the heaven and the earth. After Pangu is dead, his eyes become the sun and the moon. Thunder comes from his voice. Cloud and wind is from his breath. His body and limbs become the ground and mountain. The blood of him runs to shape the river. His flesh transforms to the soil. The insect inside his body become human. Everything in the universe comes from Pangu. This is the myth of Pangu.

After he got out from the cosmic egg, he met the saint lady Tai-yuan (聖女太元) and transformed himself as a green light into her stomach to make her pregnant. After twelve years, Pan Gu was born as a flesh human. No matter where he went to, there is a colorful cloud above him as a protection. It is an auspicious sign.

In Taiwan, there are about five temples dedicated to Pan Gu, including Kaitian temple (開天宮) in Xindian (新店), Xinzhu (新竹) separately, and Dawang gong (大王宮), Pangu temple (盤古殿), Pangu wang miao (盤古王廟) in Tainan (台南) etc.
