The 1999–2000 Botswana Premier League, also known as the 1999–2000 Castle Super League for sponsorship reasons, was the 23rd season of the Botswana Premier League. It was played from 4 September 1999 to 17 May 2000.
Mogoditshane Fighters, who were the defending champions, would go on to successfully defend both the league title[1] and the FA Cup.[2] The season was also marked by the relegation of former champions Gaborone United.
Due to the transitional nature of the 1999 season, there were no changes for the 1999–2000 season.[3]
