Jorrit Kelder (Hoorn, 1980), is a Dutch archaeologist and ancient historian. He is known especially for his work on Mycenaean political structures, and in particular his argument (first proposed in 2005 and elaborated on in a 2010 monograph) that the Mycenaean world was a single, unified state (rather than a patchwork of culturally similar, yet politically independent palace states, as had hitherto been proposed). Though his professional career is in academic policy and administration, he has held, and continues to hold, various (honorary) affiliated positions. He was a visiting professor in Greek Archaeology at Ghent University in the 2019-2020 academic year, a guest researcher and adviser at Leiden University, and an associate member of the sub-faculty of Near and Middle Eastern Studies
