Gale de Giberne Sieveking (26 August 1925 – 2 June 2007) was a British prehistoric archaeologist, best known for his work on flint and flint mines, particularly at sites such as Grimes Graves. He "played... an important part in the development of archaeology as a discipline" and particularly in the understanding of the prehistoric period. He was the son of BBC-pioneer Lancelot "Lance" De Giberne Sieveking, and half-brother to Fortean-writer Paul Sieveking.
