Iñaki Ochoa de Olza was a Spanish climber. Ochoa de Olza took part in more than thirty separate climbing expeditions in the Himalayas over the course of his career, and was involved in more than 200 expeditions as a guide. His records included climbing 12 of the world's 14 tallest mountains without the aid of oxygen. Ochoa went on record as saying that he did not believe in using oxygen to climb mountains, claiming "if you use oxygen, you are not an alpinist; you are more of an astronaut or a scuba diver.". He died of pulmonary edema in May 2008 while climbing Annapurna.

Annapurna is a mountain situated in the Annapurna mountain range of Gandaki Province, north-central Nepal. It is the 10th highest mountain in the world at 8,091 metres (26,545 ft) above sea level and is well known for the difficulty and danger involved in its ascent.
