Mummies 317a and 317b were the infant daughters of Tutankhamun, a pharaoh of the Eighteenth Dynasty of Egypt. Their mother, who has been tentatively identified through DNA testing as the mummy KV21A, is presumed to be Ankhesenamun, his only known wife. 317a was born prematurely at 5–6 months' gestation, and 317b was born at or near full term. They are assumed to have been stillborn or died shortly after birth.

They were buried in their father's tomb in the Valley of the Kings, which was discovered by the Egyptologist Howard Carter in 1922. Their bodies were mummified and wrapped in the same style as high-status adults and 317a was fitted with a gilded mummy mask; 317b's mask was too small for her and was found in 1907 among the leftovers from Tutankhamun's mummification and funerary feast cached in KV54. Each girl was buried in miniature two-coffin sets of the same design used by nobility. Both babies were unnamed, as the coffin inscriptions call them only the "Osiris", a generic term for the deceased, so they are known by the numbers assigned by Carter during his excavation.

They have been examined several times since their discovery. 317a was unwrapped by Carter in 1925 and both mummies were examined by the anatomist Douglas Derry in 1932. X-ray imaging and serological testing was carried out on 317b in the 1970s and both were CT-scanned in 2008, where the remains were found to be in a fragile and degraded condition. No cause of death could be determined for either child and neither child had any observable conditions or diseases. The 1970s diagnosis of 317b with conditions such as Sprengel's deformity and spina bifida was determined to be a result of post-mortem fracturing and dislocation of bones.
