TheChicago Assyrian Dictionary (CAD) orThe Assyrian Dictionary of the Oriental Institute of the University of Chicago is a nine-decade project at theUniversity of Chicago's Oriental Institute (now known as theInstitute for the Study of Ancient Cultures) to compile a dictionary of theAkkadian language and its dialects. Modeled on theOxford English Dictionary, work on the project was initiated in 1921 byJames Henry Breasted, the founder of the Oriental Institute, who had previously worked on theBerlin dictionary ofAncient Egyptian.

From 1973 to 1996,Erica Reiner was editor in charge, followed byMartha T. Roth, dean of humanities.^[1] Initially expected to take 10 years to complete, the first volume was not published until 1956, and the 26th and final volume was published in 2011.

At a conference at the Oriental Institute on June 6, 2011, scholars assessed the significance of the dictionary.^[2] Gil Stein, director of the Oriental Institute, said it "is an indispensable research tool for any scholar anywhere who seeks to explore the written record of the Mesopotamian civilization."^[2] It is one of several large-scale United States dictionary projects for ancient Middle Eastern languages, including theChicago Hittite Dictionary, thePennsylvania Sumerian Dictionary, and theComprehensive Aramaic Lexicon.^[3]
