The Aden Emergency, also known as the 14 October Revolution or the Aden Insurgency, was an armed rebellion led mainly by the National Liberation Front (NLF) and the Front for the Liberation of Occupied South Yemen (FLOSY) against the British Protectorate and Federation of South Arabia. It began on 14 October 1963 when tribes from Radfan attacked British troops and ended with the proclamation of independence of the People's Republic of Southern Yemen.

The British had declared a state of emergency following the throwing of a grenade at a gathering of British officials on 10 December 1963 at RAF Khormaksar. A state of emergency was then declared in the British Crown colony of Aden and its hinterland, the Aden Protectorate. The emergency escalated in 1967, hastening the end of British rule in the territory, which had begun in 1839.
