Gordon Williamson (born 1951) is a British military historian. Williamson spent seven years with the Military Police in the British Territorial Army and, as of 2016, resides in Scotland. Williamson has written more than 40 books and other publications. His works have focused on topics ranging from U-boats, military insignia, flying aces, the Waffen-SS, and special forces. Williamson has authored over 20 books on the Waffen-SS and the Wehrmacht. S. P. MacKenzie has characterized Willamson's treatment of the Waffen-SS as somewhat skeptical but still rehabilitory in nature, noting that he was one of the British historians in the 1990s who wanted "to restore the tarnished reputation [of the Waffen-SS] and reiterate its superb fighting qualities" by relying on veterans' narratives.
