Ennedi Ouest Department (Arabic: إنيدي الغربية) was a department of the former Borkou-Ennedi-Tibesti region in Chad. Its capital was Fada.
In 2008, the former Ennedi Ouest and Ennedi Est departments of Borkou-Ennedi-Tibesti became the Ennedi Region. This however would not last long as 4 years later in 2012, the Ennedi region would be split into the Ouest and Est parts. The city of Fada is now located in the Ennedi Ouest Department department of the Former Ennedi region.
