Nina Betschart (born 14 October 1995) is a Swiss professional beach volleyball player. She won the gold medal at the first ever European Games in 2015. As primarily a defence specialist; Betschart has enjoyed a lot of success in junior level, being twice an U21 World Champion and a four-time gold medallist in European Underage Championships, twice in U20 and twice in U22 level.
Betschart was born in Steinhausen, Switzerland. She began her career in indoor volleyball at VBC Steinhausen with her friend Nicole Eiholzer. Later, Betschart and Eiholzer formed a beach volleyball duo under the supervision of the coach Kurt Brunner, the first and only coach of the pair. From 2008 to 2013 they won the Swiss Junior Championships in every category they competed: U15 (2008, 2009), U18 (2010) and U21 (2011, 2012, 2013).
In 2011, along with Eiholzer, they became fifth in the U19 World Championships in Umag. They reached the final at the U18 European Championships in Vilnius but lost to home favorite top-seeded Dumbauskaitė / Povilaityte in three sets (17–21, 22–20, 13–15) and settled for silver medal. For the U21 World Championships in Halifax, Betschart teamed up with Joana Heidrich after replacing Heidrich’s original teammate Anouk Vergé-Dépré who was unable to play in the World Championships due to health reasons, and they became the U21 World Champions after defeating Canada’s top-seeded Altomare / Humana-Paredes in three sets. They were the first Swiss pair to claim the World Junior Championship title and at 15 years and 10 months, Betschart became the youngest player to win a gold medal in the history of FIVB U21 World Championships. After their international success, Betschart and Heidrich appeared on the cover of September 2011 issue of Swiss Volley magazine.
