The Strategikon of Kekaumenos (Greek: Στρατηγικὸν τοῦ Κεκαυμένου, Latin: Cecaumeni Strategicon) is a late 11th century Byzantine manual offering advice on warfare and the handling of public and domestic affairs.

The book is valuable to historians for its portrayal of the mindset of the Byzantine provincial aristocracy in the closing decades of the 11th century, and especially the social relations, as revealed in the third part. It also contains much otherwise unknown information about historical events, and is the first book to record the presence of the Vlachs in Thessaly.
