South Africa beat Australia by five wickets through a superb team effort at Lord's, the home of cricket.
The win was built around excellent performances by the batsmen in the second innings.
There was the brilliant batting by Aiden Markram who scored 136 and the captain, Temba Bavuma with his 66 runs.
Their match-winning partnership was pivotal in the team's success.
The bowlers, led by Kagiso Rabada, also kept the pressure on the Australian batsmen and never allowed them to dominate.
President Ramaphosa said, "Coach Shukri Conrad, captain Bavuma and the team have done South Africa proud. They started the match as underdogs but that indomitable spirit, that is a characteristic of our nation, carried the team through.
"The Proteas underlined the importance of being focussed on the field and triumphed.
"Your win is a major boost for cricket in South Africa and you have inspired a new generation of cricketers.
"I call on the nation to come and greet the Cricket World Champions when they arrive back in the country this week."
Aiden Markram believes South Africa's victory in the ICC World Test Championship Final has finally laid to rest the long-standing "chokers" tag - and hopes the Proteas' triumph can inspire a new generation to prioritise Test cricket.
Australia head coach Andrew McDonald believes batter Marnus Labuschagne has a big role to play for the Baggy Greens but conceded he has had a tough time of things over the past couple of seasons.
Captain Temba Bavuma wants the Proteas to follow up their World Test Championship trophy success with a sustained a period of dominance in the longest format.
This Proteas team have forever written their names in the folklore of South African cricket after beating Australia by five wickets at Lord's to capture the ICC World Test Championship mace.
