Mizael Conrado has been elected to replace Andrew Parsons as President of the Brazilian Paralympic Committee (CPB).
Conrado, the vice-president during Parsons' two terms in the role, becomes the first Paralympic medallist to take the top role at the CPB.
He won two Paralympic Games gold medals in five-a-side football at Athens 2004 and Beijing 2008.
Naise Pedrosa and Ivaldo Brandao have been chosen as first and second vice-presidents respectively.
"Being elected as President of CPB is a very emotional moment to me," said Conrado.
"I acknowledge the challenges to come, but even bigger will be our responsibilities.
"This responsibility comes with the commitment to giving my best in order to give a chance to those who have not yet had access to the Paralympic Movement.
"I want to honour the magnitude of this Movement and also honour the other Presidents who paved the way for us.
"Former President Andrew Parsons left a legacy of harmony in the Paralympic Movement and I am committed to keeping it.
"Together we will be stronger."
Parsons is widely seen as the favourite to replace Sir Philip Craven as President of the International Paralympic Committee (IPC).
Sir Philip, who has led the governing body since 2001, is due to stand down at the IPC General Assembly in Abu Dhabi on September 7 and 8.
Parsons, in charge of the CPB during last year's Paralympic Games in Rio de Janeiro and is currently a vice-president of the IPC, has not formally declared his intention to stand as candidates are not allowed to do so until nominations close on June 7.
"I want to wish best of luck to our new Board," said Parsons.
"They are three extremely capable people.
"I have worked side by side with Brandao and Mizael.
"Mizael's perspective as a former athlete, put together with his experience as a vice-president will make him a great President.
"I'm sure he will lead our Paralympic Movement not only to the top of medal tables but will also open doors to people with impairments in all levels."
