Tutankhamun was an Egyptian Pharaoh of the Eighteenth dynasty (ruled 1333 BC – 1324 BC), during the period of Egyptian history known as the New Kingdom. Cleopatra VII Philopator was a Hellenistic ruler of Egypt (ruled 69 BC – 30 BC), originally sharing power with her father Ptolemy XII and later with her brothers/husbands Ptolemy XIII and Ptolemy XIV; eventually gaining sole rule of Egypt. The Ptolemaic dynasty (sometimes also known as the Lagids, from the name of Ptolemy I's father, Lagus) was a Hellenistic Macedonian royal family which ruled the Ptolemaic Empire in Egypt for nearly 300 years, from 305 BC to 30 BC. Ptolemy, one of Alexander the Great's deputies, was appointed satrap of Egypt after Alexander's death in 323 BC. So, no, there was absolutely no relationship at all between King Tut and Cleopatra. In fact, Cleopatria was the first ruler of Egypt in 300 years (since the Greeks took over) who even bothered to learn the Egyptian language!
