The Bani Bu Ali expedition (1820–21) was a punitive campaign launched by the Sultan of Muscat and the East India Company against an Omani tribe known as the Bani Bu Ali in southeastern Arabia. It consisted of two expeditions. The first was the only land campaign Said bin Sultan conducted in Arabia during his long reign. It included a small allied British force and was defeated. The second, led by a more substantial British component, resulted in a decisive victory over the Bani Bu Ali. Company units engaged in the expedition received the "Beni Boo Alli" battle honour.
