José Carlos Ribeiro de Carvalho Guimarães (born 9 April 1964 in Luanda), known as Zé Carlos, is a former Angolan basketball player and a former coach of the Angola national basketball team.

He achieved a huge success in his career playing for Portuguese side Benfica, where he won several National Championship and the Cup of Portugal titles, with his fellow countryman Jean-Jacques.

On a press conference held on May 31, 2013, Guimarães said he is considering abandoning all basketball-related activity due to the disrespectful manner that some individuals - whom he did not name - handled the case of his dismissal.

Guimarães learned of his dismissal, with the announcement by the Angolan Basketball Federation in a previous news conference, of Paulo Macedo as the new head coach.

Guimarães has been offered, instead, a job as an advisor to the chairman of the Angolan Basketball Federation, Paulo Madeira, which he declined.
