Willi Schulz (born 4 October 1938) is a German former footballer who played as a defender for Schalke 04 and Hamburger SV.

He played his first of altogether 66 games for West Germany in 1959 at a time when he was still an amateur for lower league club Union Günnigfeld.

During the 1966 World Cup, Schulz acted as the sweeper of the West Germany national team, a role he had taken over from Klaus-Dieter Sieloff only shortly before the tournament.

He was noted for his calmness even under pressure, his positional play, his strength at man-to-man duels, his solid passing game, aerial ability and a special expertise at sliding tackling.

After his retirement, Schulz established an insurance agency in Hamburg and also engaged in the slot machine business.
