Tomb KV21 is an ancient Egyptian tomb located in the Valley of the Kings in Egypt. It was discovered in 1817 by Giovanni Belzoni and later re-excavated by Donald P. Ryan in 1989. It contains the mummies of two women, thought to be Eighteenth Dynasty queens. In 2010, a team headed by Zahi Hawass used DNA evidence to tentatively identify one mummy, KV21A, as the biological mother of the two fetuses preserved in the tomb of King Tutankhamun.
