Pepi I Meryre (reigned 2332 - 2283 BC ) was the third king of the Sixth dynasty of Egypt.

Pepi was the son of Teti and needed the support of powerful individuals in Upper Egypt in order to put down a usurper and gain his rightful throne. These individuals would remain a strong presence in his court thereafter, and two of his queens were daughters of his Upper Egyptian vizier. His reign was marked by aggressive expansion into Nubia, the spread of trade to far-flung areas such as Lebanon and the Somali coast, but also the growing power of the nobility. His mortuary complex gave name to Memphis.
