Agisymba was an unidentified country in Africa mentioned by Ptolemy in the middle of the 2nd century AD. According to Ptolemy's writings it was a 4 months journey south of the Fezzan and contained large animals, such as rhinoceroses and elephants, as well as many tall mountains. Ptolemy's account is based on that written by Marinus of Tyre between 107 AD and 115 AD. Between the years 83 AD and 92 AD, the king of the Garamantes claimed that the Agisymba population were his subjects. Modern historians suggest that Agisymba was probably somewhere to the north of Lake Chad as the Chad area is populated with many mountains. One theory is that Agisymba was an antecedent of the Kanem Empire located on the northern shore of Lake Chad.
