Luís Manuel Ribeiro de Castro is a former Portuguese football player and current manager of the Primeira Liga football club F.C. Porto.

For much of his childhood and youth, Castro suffered from a debilitating disease. Castro is a graduate from the University of Coimbra, where he majored in Physics.

One year after retiring from professional football, Castro began his career as football manager with former club R.D. Águeda, where he would remain for two seasons. Following his spell with Águeda, Castro went on to manage G.D. Mealhada, C.D. Estarreja and A.D. Sanjoanense, before getting his big break in 2004, where he was appointed manager of F.C. Penafiel, as a replacement for Manuel Fernandes.

His first season with the newly promoted Rubro-Negros saw him guide his side to an 11th place in the national championship. Castro's most notable victory, which helped his side claim an 11th place finish, came on the 7 May 2005, when Penafiel defeated S.L. Benfica.

His second season with the Penafidelenses proved to be disastrous, as his side was relegated back to the Liga de Honra, with a record number of 15 points and only managed to win two league matches during the season. Penafiel's season was further dampened by its humiliating 4–0 defeat in the Taça de Portugal at the hands of F.C. Lixa.

Following Penafiel's relegation, Castro left the club. In the 2006–07 season Castro became manager at FC Porto's youth academy, where he would remain until 2013, before managing Porto's reserve side.  On March 5, 2014, following the resignation of Paulo Fonseca, Luís Castro was named interim as the new coach of the first team until the end of season.
