Kaédi (Arabic: كيهيدي‎) is a city of over 60,000 people and is the largest city and administrative center of the Gorgol region of Southern Mauritania. The city is located 16.150 degrees latitude and -13.500 degrees longitude, and is approximately 435 km from Mauritania's capital, Nouakchott.

The city sits within the "Chemama" Riverine zone along the north bank of the River Senegal where the river connects with the Gorgol River. This region is one of the few areas of settled agriculture in the country. Culturally, the city is among the most diverse in Mauritania, consisting of ethnic "White Moors" (Arabic: البيضان) "Black Moors" (Arabic: السودان) as well as Pulaar, and Soninke communities.

It is known as a market town a medical centre, and a centre for local farmers. The market is considered as one of the more interesting in Mauritania, but reflects sub-saharan culture of neighboring Senegal somewhat more than the Moorish/Arabic culture found further north in the country.

Most of the architecture consists of brown, flat-roofed buildings, undistinguished except for the fact that most are surrounded by "dutch brick" enclosures. The one exception is the unusual architecture of the Kaédi Regional Hospital, which was constructed in 1989 and features multiple beehive-style domes. The award winning architecture was designed by ADAUA, the Association for the Development of Traditional African Urbanism and Architecture, which aims to develop indigenous African urban architectural designs using local materials and technologies.
