Sumuel or Sumu-El (, su-mu-el3; died 1866 BC) was the Amorite King of Larsa, a city-state in Sumer, in southern Mesopotamia, from c. 1895-1866 BC (MC).
Annals for his complete 29-year reign have survived. He was preceded by Abisare.
He campaigned against Akusum and Kazallu in his year 4, Uruk in year 5, Pinaratim in year 8, Sabum in year 10, Kish in year 11, Kazallu in year 15, Nanna-Isha in 16, and Umma at the end of his reign. Most of these seem to be names of small villages along the Euphrates.
Sumuel is known from several inscriptions.
