A corn mummy or germinating Osiris^[1] is an Ancient Egyptian sculpture of Osiris that contained germinated grain seeds, commonly wheat or barley.^[2][3][4] The rest of the mummy was made up of other materials such as wax, sand and earth.^[2][3] They were fitted with masks most commonly made of wax but sometimes silver.^[5] The mummies were provided with wooden coffins.^[2][3]

They seem to have been buried as part of certain festivals such as Khoiak.^[2][3] They were also buried in tombs as part of funerary paraphernalia, with a notable example being found in the tomb of Horemheb, KV57, in the Valley of the Kings.^[6]
