Luís Manuel Ribeiro de Castro (born 3 September 1961) is a Portuguese football manager and former player who played as a right-back.

[6] One year after retiring from professional football, Castro began working as a manager with his final club Águeda, where he would remain for two seasons.

He went on to be in charge of lowly Mealhada [pt], Estarreja and Sanjoanense, before being appointed at Penafiel in the top tier in summer 2004[7] and guiding it to the eleventh position in his debut campaign,[4] the highlight being a 1–0 home win against Benfica.

[11] He then managed three sides in the Portuguese top flight after leaving for Rio Ave in November 2016,[12] going on to Chaves[13] and Vitória de Guimarães.

[14] In May 2019, at the end of his only campaign at the Estádio D. Afonso Henriques, he secured for them fifth place and a spot in the UEFA Europa League at the expense of neighbours Moreirense.

[15] On 12 June 2019, Castro signed a two-year contract at Shakhtar Donetsk as a replacement for compatriot Paulo Fonseca who left for Roma after winning three Ukrainian Premier League championships in a row.

[35] In spite of star player Cristiano Ronaldo leading the scoring charts with a league all-time best 35 goals, his side finished second to the same opposition,[36] losing the final of the King's Cup against that very team following a penalty shootout.
