Nikephoros Euphorbenos Katakalon (Greek: Νικηφόρος Εὐφορβηνός Κατακαλών) was a Byzantine aristocrat and son-in-law of Emperor Alexios I Komnenos (r. 1081–1118).
He was the son of the distinguished general Constantine Euphorbenos Katakalon, one of Alexios' most trusted officials.
As a token of Alexios' appreciation for Constantine, Nikephoros was married to the porphyrogennete Maria, the emperor's second daughter, and raised to the rank of panhypersebastos.
[3] With Maria, he had numerous children, but only two sons, Alexios Komnenos and Andronikos, are known by name, having held senior positions later in the century.
[5] The couple also had an unknown number of daughters (at least three according to Varzos), as their existence is mentioned in the typikon of the Kecharitomene Monastery.
