Previously known as the South African Tennis Association, the change was announced by Wire Zondi, TSA's president in Johannesburg on Tuesday.
"To conform to worldwide trends and after much discussion, deliberation and investigation, the TSA Board decided on the name change," said Zondi.
"We found we were continuously being referred to as Tennis South Africa, both locally and internationally, so it made sense for us to make the change."
TSA had also made changes to its executives on the board and looked forward to a new era.
"I am a new President, we have a new Board and with the new name we are ready to face the challenges and give the game of tennis new life in our country," added Zondi.
TSA also unveiled their new logo, depicting the energy, power and movement of a tennis serve.
The colours mirror those of the South African flag and reinforce the fact that TSA stands proud as the governing body for tennis in this country.
