Sneferka is the serekh-name of an early Egyptian king who may have ruled at the end of 1st dynasty. The exact length of his reign is unknown, but thought to have been very short and his chronological position is unclear.

Sneferka´s serekh-name is object of investigations, because the unusual typographical order of the hieroglyphic sign within the serekh led to several different readings: His name is read as Seneferka, Sneferka, Neferseka and Sekanefer. Egyptologist Francesco Tiradritti reads Neferkaes while thinking that Sneferka might have been a ruling queen.

The serekh-name "Sneferka" appears on several schist- and alabaster vessels. One was found in the mastaba of the high official Merka who served under king Qa'a; a second one in the underground galleries of the step pyramid of king Djoser (3rd dynasty) and the third was found in a anonymous mastaba, also at Sakkara. A fourth artifact with Sneferka's name is found in the private Georges-Michailidis-Collection and is questioned by Archaeologists and Egyptologists in its authenticity, because no find spot were noticed. In addition the inscription on the Michailidis-object shows a serekh with no Horus-falcon, which would be highly unusual for any Egyptian artifact.
