Eustathios Daphnomeles (Greek: Εὐστάθιος Δαφνομήλης, fl. early 11th century) was a Byzantine strategos and patrician who distinguished himself in the Byzantine conquest of Bulgaria. He ranks as one of the most prominent and successful generals in the thirty-year war between Emperor Basil II (r. 976–1025) and Samuel of Bulgaria (r. 997–1014), helping to end the long conflict by blinding and capturing the last Bulgarian leader, Ibatzes, in 1018.
