Reinhard "Stan" Libuda (10 October 1943 in Wendlinghausen near Lemgo – 25 August 1996 in Gelsenkirchen) was a German footballer playing on the right wing.
His tremendous skill as a dribbler was a major factor in Borussia Dortmund's 1966 UEFA Cup Winners' Cup championship and West Germany’s hard-won qualification and its third-place finish in the 1970 FIFA World Cup. In the UEFA Cup Winners' Cup Final in 1966 he scored the final goal against Liverpool F.C. to earn a 2–1 extra time victory for Dortmund.
Libuda played for FC Schalke 04 from 1961 until 1976 with two interruptions: from 1965 until 1968 he played for Borussia Dortmund, and 1972–73 for RC Strasbourg.
Between 1963 and 1971, Libuda gained 26 caps for the Germany national football team and scored three goals. In the German Fußball-Bundesliga he played 264 games and scored 28 goals for FC Schalke 04 and Borussia Dortmund.
Later he was involved in the Bundesligaskandal of 1971. The shy Libuda later suffered from cancer, and died from the complications of a stroke.
Libuda gained his nickname "Stan" after the English player Stanley Matthews who played in the same position and who was widely praised for his dribbling skills.
