The Paphlagonian expedition of the Rus' was an attack by the Rus' on cities on the Propontis (Sea of Marmara) and on the coast of the Paphlagonia, marking the first known contact between the Rus' and the Byzantine Empire. Its date is questioned, as is the belief that it was distinct from the Rus'–Byzantine War (860).
