Manfred Bietak (born 6 October 1940, Vienna) is an Austrian archaeologist. He is Professor emeritus of Egyptology at the University of Vienna and Director of the Austrian Archaeological Institute in Cairo 1973-2009. He is currently Chairman of the Vienna Institute of Archaeological Science at the University of Vienna and Chairman of the Commission for Egypt and the Levant at the Austrian Academy of Sciences. In 1997 and 2006, he was Visiting Professor at the Collège de France; in 2004, he was Martha Whitcomb Visiting Professor at Harvard.

Bietak is best known as the director of the Austrian excavations at two sites in the Nile delta: Tell El-Dab'a, which was the location of Avaris, the capital of the Hyksos period; and Piramesse, which was the capital of the Nineteenth Dynasty of Egypt. The site was also most probably the naval base Peru-nefer of Thutmosis III and Amenhotep II. A palace precinct of those kings, furnished with Minoan frescoes was one of the most important discoveries. Bietak has also conducted excavations in western Thebes (Luqsor), where he discovered the huge tomb of Ankh-Hor, Chief steward of the Divine Wife of Amun Nitokris (26th Dynasty).
