Bayirbujak (; ), also known as West Turkmeneli (), is a region in northwestern Syria. It is viewed as the Syrian Turkmen homeland. Bayñrbucak is divided into Bayñr and Bucak, and includes the main settlements of Kessab, Ras al-Bassit, Umm al-Tuyour, Burj al-Islam, Ghimam, as well as the Turkmen Mountain region. Bayñrbucak borders Hatay Province to the north, Jabal al-Akrad to the east, Latakia city to the south, and the Mediterranean Sea in the west.
Bayñrbucak is a Turkish exonym, and not the official name for the region, which is Al-Rabiaa subdistrict. The word Bayñrbucak comes from two different words in Turkish: bayñr (en: hillside) and bucak (en: district). According to Ottoman archival documents, Bayir was the official name of the district (nahiye) in the Ottoman period. It is sometimes referred to as West Turkmeneli to distinguish from the Iraqi Turkmen homeland, known as East Turkmeneli.
On 24 November 2015, two Turkish F-16s shot down one of two Russian Su-24 fighter jets, which violated Turkish airspace while in an operation to attack a Turkmen rebel militia in Bayñrbucak. One Russian pilot was killed by Turkmen forces under the command of Alparslan ÃÂelik.
Heavy Russian aerial bombardments during the 2015âÂÂ16 Latakia offensive resulted in a very difficult situation in the Bayñrbucak Turkmen regions, causing almost all Syrian Turkmens to flee the region to Turkey. The Syrian government of Bashar al-Assad began a policy of settling Alawites into the houses of Turkmen civilians who had fled the region.
In early July 2025, wildfires swept through the Bayñrbucak region, including Qastal Ma'af and al-Furnloq Reserve, destroying over 14,000 hectares of forest and farmland. Villages were evacuated as the fires, driven by extreme heat, drought, and strong winds, spread rapidly through the rugged terrain. Efforts to contain them were hindered by unexploded ordnance and limited resources. Turkey, Jordan, and Lebanon provided firefighting support, while the UN allocated $625,000 in emergency aid. By 15 July, the fire had been contained.
