Yannick Nyanga (born 19 December 1983 in Kinshasa, Zaire) is a former professional rugby union player who played as a flanker for Racing 92 and France, and is also known for his long tenure at Toulouse.

After holding a reserve position in France's opening wins over Scotland and England during the 2005 Six Nations, he was called up into the starting line-up for the remainder of the tournament; playing Wales, Ireland and Italy.

Following Béziers' relegation to Rugby Pro D2, Nyanga was signed by top club the then Heineken Cup champions Stade Toulousain for the upcoming season.

Nyanga was then capped another three times at the end of the year, in the win over Australia in Marseille, Tonga in Toulouse, as well as the 50 to six victory over Canada in Nantes, though he was partly rested, used as a reserve.

Nyanga shares the cover of the French version of the EA Sports game Rugby 08 with All Blacks captain Richie McCaw.
