Abdirahman Ahmed Ali Tuur (Somali: Cabdiraxmaan Axmed Cali Tuur, Arabic: عبد الرحمن أحمد علي الطور) (var. "Tur", "Tour", meaning "Hunchback"^[6]) (November 6, 1931 - November 8, 2003) was a Somali politician who served as the first President of Somaliland from 1991 to 1993. Tuur previously served as the Chairman of the Somali National Movement from 1990 to 1991. He also served as the Vice President of Somaliland from 1993 to 1995.

Tuur was born on November 6, 1931, in Burao, then a part of the British Somaliland protectorate. He hailed from the Muse Arreh sub clan of the Garhajis.^[7]

He was one of the top student that graduated from the first Intermediate School in British Somaliland Protectorate and was given a scholarship to Sudan in 1948 to study at the renowned Hantoob secondary School. In Hantoob, he met and befriended with some of the future Sudanese leaders like Jaafar Nimeiry, Sadiq Al-Mahdi and Hassan Al-Turabi. Abdirahman excelled both in sports (especially football and track) and in academic studies. He later received an additional scholarship to study at the University of Exeter.

After successfully completing his university in the UK, Abdirahman returned and started his career as an Administrative Officer in Borama in 1956 and was elevated to the position of District Commissioner (DC) 3 years later (1959). In 1961 he became Governor of the Eastern Region (Burao) and then in 1964 the Governor of Western Region (Hargeisa). In that same year he joined the Ministry of Foreign Affairs where he was appointed in the following diplomatic posts:

• Sudan 1964-1968 and 1970-1971 Ambassador
• Ethiopia 1972-1977 Ambassador
• East Germany 1978-1981 Ambassador
• UAE 1981-1983 Ambassador

He later became the Chairman of the Somali National Movement (SNM), a guerilla force mainly drawn from his Isaaq clan, which was attempting to topple former President of Somalia Siad Barre's military regime. Although the SNM at its inception had a unionist constitution, it eventually began to pursue a separatist agenda, looking to secede from the rest of Somalia. Under Tuur's leadership, the local administration declared the northwestern Somali territories independent on 18 May 1991. He then became the newly established Somaliland's first President, but subsequently renounced the separatist platform in 1994. Tuur concurrently began instead to publicly seek and advocate reconciliation with the rest of Somalia under a power-sharing federal system of governance.^[8] In doing so, he also represented the interests of many other Isaaq members, who were against secession.^[7] Tuur additionally lent some support to the UNOSOM peace-building mission in the southern regions.^{[9][better source needed]}

Tuur died on November 8, 2003, at the age of 72 and was buried in Burao, Somaliland.^[10]
