Two teams from Brazil, plus sides from Chile and Colombia, will compete in the Premier section of the SuperCupNI youth football tournament at the end of July.
The oldest club in Brazil, Ponte Preta, will be represented at the competition for the first time, along with Ascasco Audax, who also hail from Sao Paulo.
Chile's O'Higgins and the Alset Academy from Bogata in Colombia will also take part in the Premier competition.
Central America will be represented by Club America from Mexico.
"There is always a special buzz around South American teams at our event and Brazilian sides in particular," commented tournament chairman Victor Leonard.
"We have established excellent relations with them over the years and had winners in Fluminense and Desportivo in the past at this level, while Corinthians won the Junior event two years ago."
Club sides from Vitoria and Botafogo have also competed in the past as well as national representatives in the former Elite competition which Vitoria won way back in 1999.
"Our supporters love the exciting brand of football these teams always bring and the young people have a wonderful time experiencing a different way of life in Northern Ireland when they spend time with us," added Victor
The Premier and Junior competitions will kick off on Monday, July, 25, following a welcome parade of teams in Coleraine the night before and the running of the inaugural Under-21 tournament featuring Celtic, Real Sociedad, Benfica and Everton, the previous Thursday and Saturday.
