Sobek was an ancient Egyptian deity with a complex and elastic history and nature. He is associated with the Nile crocodile or the West African crocodile and is represented either in its form or as a human with a crocodile head. Sobek was also associated with pharaonic power, fertility, and military prowess, but served additionally as a protective deity with apotropaic qualities, invoked especially for protection against the dangers presented by the Nile. Sobek has been famed for having been revered by the first female Pharaoh by the Nebty name Sat-Sekhem-Nebet-Tawy Sobekneferu, present both in the female Pharaoh's nomen, Sobekneferu, and her praenomen Kasobekre.

Ancient Egyptian deities are the gods and goddesses worshipped in ancient Egypt. The beliefs and rituals surrounding these gods formed the core of ancient Egyptian religion, which emerged sometime in prehistory. Deities represented natural forces and phenomena, and the Egyptians supported and appeased them through offerings and rituals so that these forces would continue to function according to maat, or divine order. After the founding of the Egyptian state around 3100 BC, the authority to perform these tasks was controlled by the pharaoh, who claimed to be the gods' representative and managed the temples where the rituals were carried out.
