Alexios Mosele (Greek: Ἀλέξιος Μωσηλέ), or Musele/Mousele (Greek: Μουσηλέ), was a Byzantine admiral (droungarios tou ploimou) in the early reign of Emperor Romanos I Lekapenos (r. 920–944). He was killed in 922, leading a detachment of imperial marines along with the imperial tagmata under the domestikos ton scholon, Pothos Argyros, against the forces of the Bulgarian tsar, Simeon I (r. 893–927). The Byzantines were defeated at the Battle of Pegae, and Mosele drowned while trying to escape.
