Nina Caprez, born November 15, 1986 in Küblis, is a Swiss climber, double Swiss champion in 2006, for the speed and difficulty events, and twice finalist, at the Swiss Cup (CSC) in bouldering.

She was the companion of Swiss climber Cédric Lachat for 10 years until 2015. Nina Caprez grew up in Küblis, and is the youngest of three children, she has a brother and a sister. Her father died of a fatal fall while hiking, when she was only three years old. She started climbing at 13, and discovered sport climbing at 17. At 19, she became a member of the national team. Between 2006 and 2009, she won five world cup events in bouldering and rock. In 2008, she decided to leave the competition in 2009, because she felt she did not have enough competitive spirit, and did not conceive the practice of climbing, to fight against others.

She has since made spectacular ascents, with photos and films, which has the advantage of being able to live from her passion and work as a team.
