Teun Floris de Nooijer (born 22 March 1976 in Egmond aan den Hoef) is a field hockey player from the Netherlands, who twice became Olympic champion with the Dutch national squad: in 1996 and in 2000. He currently plays for Dutch side HC Bloemendaal.

He made his debut on 4 June 1994 in a friendly match against New Zealand. Since then the midfielder played over three hundred international matches for the Dutch. On April 4, 2007 he earned his 350th cap for the Netherlands national field hockey team, when the team defeated Belgium (7-3) in a friendly in Boxtel, Noord-Brabant.

De Nooijer started playing hockey at the age of nine, with his brothers in the backyard of their house. He joined HC Alkmaar at the age of eleven, and was selected for the Dutch under-16 team 2 years later. At fifteen, De Nooijer made his debut in the senior men's league with HC Alkmaar, and two years later, he first played in Holland's elite league with HC Bloemendaal. After two seasons wearing the number 11 shirt, De Nooijer switched to the number 14, made famous by Johan Cruijff, and has worn it for club and country ever since. The number was later bestowed on the signature stick he helped to create, the Dita Giga #14
