Letopolis (Greek: Λητοῦς Πόλις) was an ancient Egyptian city, the capital of the second nome of Lower Egypt.

Its Egyptian name was Khem 𓋊𓐍𓐝𓂜𓊖𓉐 (ḫm),[2] and the modern site of its remains is known as Ausim (Arabic: اوسيم, from Coptic: ⲟⲩϣⲏⲙ, ⲃⲟⲩϣⲏⲙ).

[3][4][5] The city was a center of worship of the deity Khenty-irty or Khenti-kheti, a form of the god Horus.

The site and its deity are mentioned in texts from as far back as the Old Kingdom (c. 2686–2181 BC), and a temple to the god probably stood there very early in Egyptian history.

[6][4] Letopolis is depicted in the 2017 video game Assassin's Creed Origins,[7] set during the Ptolemaic Era of Egypt,[8] as having been "rediscovered" and used as a base by one of the games antagonists.
