Iván Raña Fuentes (born 10 June 1979) is a Spanish triathlete and the winner of three medals in the World Triathlon Championships between the years of 2002–2004.

His world championship win in Cancún, Mexico, was Spain's first gold medal in the event.

[1] Occasionally, Raña has participated in some rally car races, having his brother José as his copilot.

In December 2008, he signed a one-year deal with the professional cycling team Xacobeo–Galicia and during the first stage of his first race, the Mallorca Challenge, he was involved in a substantial fall, which resulted in a dislocated collarbone.

After reflecting on his athletic career, Raña decided to return to the triathlon in December 2009 with the ambition of competing in the London Olympics in 2012.
