خلیج عَدَن خلیجی است در جنوب یمن که از سمت جنوب با کشور سومالی و از سوی غرب با کشور کوچک «جیبوتی» همسایه میباشد. از سمت غرب به بابالمندب و دریای سرخ و از سمت شرق با اقیانوس هند مرتبط است و جزئی از این اقیانوس بشمار میآید.
در حاشیه شمالی این خلیج در کشور یمن، شهر معروف عدن قرار دارد که از سدهها پیش بزرگترین و پررونقترین شهر سرزمین یمن به شمار میآمده و هماکنون نیز پس از صنعا پایتخت این کشور، مهمترین شهر کشور یمن است. نام این خلیج نیز از نام همین شهر گرفته شدهاست.
خلیج عدن یک ناحیه شناختهشده برای دزدیهای دریایی است که آبهای ناحیه را برای سفرهای دریایی ناامن کردهاست.
The Gulf of Aden, also known as the Gulf of Berbera, (Arabic: خليج عدن, Ḫalīǧ ʻAdan, Somali: Gacanka Berbera) is a gulf amidst Yemen to the north, the Arabian Sea and Guardafui Channel to the east, Somalia to the south, and Djibouti to the west. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, and in the southeast, it connects with the Indian Ocean through the Guardafui Channel. It shares its name with the port city of Aden in Yemen, which forms the northern shore of the gulf. Historically, the Gulf of Aden was known as "The Gulf of Berbera", named after the ancient Somali port city of Berbera on the south side of the gulf. However, as the city of Aden grew during the colonial era, the name of "Gulf of Aden" was popularized.
The temperature of the Gulf of Aden varies between 15 °C (59 °F) and 28 °C (82 °F), depending on the season and the appearance of monsoons. The salinity of the gulf at 10 metres (33 ft) depth varies from 35.3 ‰ along the eastern Somali coast to as high as 37.3 ‰ in the gulf's center, while the oxygen content in the Gulf of Aden at the same depth is typically between 4.0 and 5.0 mg/L.
Commerce and trade
The Gulf of Aden is a vital waterway for shipping, especially for Persian Gulf oil, making it an integral waterway in the World economy. Approximately 11 percent of the world's seaborne petroleum passes through the Gulf of Aden on its way to the Suez Canal or to regional refineries. The main ports along the gulf are Aden in Yemen, Djibouti City in Djibouti, Zeila and Berbera Las Khorey and Bosaso in Somalia.
In earlier history, the city of Crater, located just south of the modern city of Aden, was an important port in regional trade. Crater was the principal harbor of the pre-Islamic kingdom of Awsan, and after its annexation by the kingdom of Saba at the end of the 5th century, played a significant role in connecting Africa with Arabia.
In the late 2000s, the gulf evolved into a hub of pirate activity. By 2013, attacks in the waters had steadily declined due to active private security and international navy patrols. India receives USD 50 billion in imports and sends USD 60 billion in exports through this area annually. Due to this, and for the sake of protecting the trade of other countries, India keeps a warship escort in this area.

A geologically young body of water, the Gulf of Aden has a unique biodiversity that contains many varieties of fish, coral, seabirds and invertebrates. This rich ecological diversity has benefited from a relative lack of pollution during the history of human habitation around the gulf. However, environmental groups fear that the lack of a coordinated effort to control pollution may jeopardize the gulf's ecosphere. Whales, dolphins, and dugongs were once common before being severely reduced by commercial hunts, including by mass illegal hunts by Soviet Union and Japan in 1960s to 70s. Critically endangered Arabian humpback whales were once seen in large numbers, but only a few large whales still appear in the gulf waters, including Bryde's whales, blue whales, and toothed whales inhabiting deep-seas such as sperm whales and tropical bottlenose whales.
