Gustavo Nieves Campello (born 9 March 1982) is a Spanish T12/B2 Paralympic athlete.

[4][6][7][8] His initial preference was to study biology but his vision issues meant he could not use a microscope, so he made the academic program switch.

[11][12] Nieves competed in the 2000 Summer Paralympics in Sydney, Australia[7] where he finished sixth in the 10,000 meter race.

He was trying to get the credentials that would enable him to get a job as athletics did not provide enough money for him to live off the sport.

[6] Following the 2004 Games, more money was made available to Paralympic athletes and he was able to dedicate more time to the sport.

[3][7] Following the 2008 Games, he switched coaches to Pablo Diaz and joined Gymnastic Society of Pontevedra athletic club.

[19] In March 2012, Nieves was training up to four hours a day at the Galician Sports Modernization Center (CGTD).

[9] Prior to the start of the London Games, he trained with several other visually impaired Spanish track and field athletes in Logroño.

[21] The city of Pontevedra held a sending off ceremony prior to the start of the Games where Nieves was honoured.

[23] In May 2013, he was attempting to qualify at the Kern Sauleda Pharme-Grand Prix for the IPC Athletics World Championships in Lyon, France, in the 5,000 meter race.
