The '''Guardafui Channel''' ({{Langx|ar|مضيق غواردافوي}}, {{langx|so|Marinka Gardafuul}}) is an oceanic [[strait]] off the tip of the [[Horn of Africa]] that lies between the [[Puntland]] region of [[Somalia]] and the [[Socotra Governorate|Socotra governorate]] of [[Yemen]] to the west of the [[Arabian Sea]].<ref>Schott, Friedrich A., and Jürgen Fischer. "Winter monsoon circulation of the northern Arabian Sea and Somali Current." Journal of Geophysical Research: Oceans 105.C3 (2000): 6359–6376.</ref> It connects the [[Gulf of Aden]] to the north with the Somali[[Indian seaOcean]] to the south. Its namesake is [[Cape Guardafui]], the very tip of the Horn of Africa. Notable places of interest include the [[Alula Lagoon]].

The oceanic strait has been regarded as a possibly dangerous pitfall both during peace and war times. It was a highly strategic region during World War Two. Duedue to its possession by an Axis power at the time, Italy,. The Allies attempted to secure passage through the oceanic strait in the [[Operation Chapter]]. Subsequently, the Allies decided that in order to continue routing independent ships and convoys, air cover was needed.<ref>The Royal Indian Navy, 1612-19501612–1950 - Page 114, D. J. Hastings</ref> The oceanic strait also experiences cyclones that emerge from its southeast in the Somali sea.<ref>{{Cite web|url=https://www.upi.com/Top_News/World-News/2018/05/25/Yemen-declares-disaster-after-Cyclone-Mekunu-Oman-in-path-next/7081527247932/|title=Yemen declares disaster after Cyclone Mekunu; Oman in path next|access-date=May 26, 2018|archive-date=May 27, 2018|archive-url=https://web.archive.org/web/20180527064355/https://www.upi.com/Top_News/World-News/2018/05/25/Yemen-declares-disaster-after-Cyclone-Mekunu-Oman-in-path-next/7081527247932/|url-status=live}}</ref> There is a dispute between the Somali government and Yemen over the sovereignty of its islands.<ref>{{cite web | url=http://www.yemenpost.net/Detail123456789.aspx?ID=3&SubID=2698 | title=Follow Yemen Post daily updates on our Twitter page @YemenPostNews- Yemen Post English Newspaper Online | access-date=May 27, 2018 | archive-date=August 24, 2023 | archive-url=https://web.archive.org/web/20230824145741/http://www.yemenpost.net/Detail123456789.aspx?ID=3&SubID=2698 | url-status=live }}</ref> The presence of an archipelago has also meant that there are shores for stranded sailors to find shelter, which on occasion has subsequently resulted in their evacuations.<ref>{{Cite web|url=https://indiablooms.com/news-details/N/40457/navy-rescues-indian-nationals-stranded-in-socotra-islands-for-10-days.html|title=Navy rescues Indian nationals stranded in Socotra Islands for 10 days &#124; Indiablooms - First Portal on Digital News Management|access-date=June 16, 2018|archive-date=June 16, 2018|archive-url=https://web.archive.org/web/20180616180413/https://indiablooms.com/news-details/N/40457/navy-rescues-indian-nationals-stranded-in-socotra-islands-for-10-days.html|url-status=live}}</ref>
