The Aberdeen Bestiary (Aberdeen University Library, Univ Lib. MS 24) is a 12th-century English illuminated manuscript bestiary that was first listed in 1542 in the inventory of the Old Royal Library at the Palace of Westminster. Due to similarities, it is often considered to be the "sister" manuscript of the Ashmole Bestiary. The connection between the ancient Greek didactic text Physiologus and similar bestiary manuscripts is also often noted. Information about the manuscripts origins and patrons are circumstantial, although the manuscript most likely originated from the 13th century and was owned by a wealthy ecclesiastical patron from north or south England. Currently, the Aberdeen Bestiary resides in the Aberdeen University Library in Scotland.
