Sedullos (87 BC – 52 BC) was a Gaulish chief of the tribe of the Lemovices. He commanded the 10,000 Lemovices that formed part of the relief force led by the Arvernian Vercassivellaunos. This relief force was raised to assist Vercingetorix at the Battle of Alesia. His death and courage are mentioned by Julius Caesar in his Gallic Wars.
