Ruy Ramos (Japanese: ラモス 瑠偉, Hepburn: Ramosu Rui, born 9 February 1957), formerly Ruy Gonçalves Ramos Sobrinho (Portuguese: [ˈʁuj ɡõˈsawviz ˈʁɐ̃mus suˈbɾĩɲu]) until he obtained Japanese citizenship, is a former football player and manager, originally from Brazil, who spent his career in Japan and played for the Japan national team as a midfielder.

Ramos was an important member of the Japan national team during their unsuccessful 1994 World Cup qualification.

In September 1990, when Ramos was 33 years old, he was called up for the Japan national team for the 1990 Asian Games.

Under manager Hans Ooft, Japan progressed to the final qualifying stage of the AFC for the 1994 World Cup.

Ruy Ramos was on the pitch when Japan's hope to play in the finals was dashed by an injury-time Iraqi equaliser in the last qualifier, the match that the Japanese fans now refer to as the Agony of Doha.

In March 2005, Ramos became coach of the Japan national beach soccer team and took them to the 2005 World Cup, where they finished fourth.

The first game was on 4 March against Thespa Kusatsu, one of the weakest teams in the league, and Tokyo won this match 5-0.
