Senegal replaced Tunisia as the highest ranked African national team when the monthly statistics were released by Fifa on Thursday.
The Senegalese rose from second place on the back of a 2019 Africa Cup of Nations qualifying victory in Equatorial Guinea during November.
Tunisia lost away to Egypt in the same competition, and were also beaten at home by Morocco in a friendly.
Bafana Bafana moved up one place from 73 to 72 on the Fifa rankings, having drawn their most recent matches against Nigeria and Paraguay.
Only five African countries – Senegal, Tunisia, Morocco, Nigeria and the Democratic Republic of Congo – were among the top 50 in the world.
