The Theme of Strymon (Greek: θέμα Στρυμόνος) was a Byzantine military-civilian province (theme) located in modern Greek Macedonia, with the city of Serres as its capital. Founded probably by the mid-to-late 9th century, its history as an administrative history was chequered, being variously split up and/or united with neighbouring themes.
