Gabriela Koukalová, née Soukalová (Czech pronunciation: , born 1 November 1989, Jablonec nad Nisou, Czechoslovakia) is a former Czech biathlete. She won two Olympic silver medals at the 2014 Sochi Games and she is a two-time World Championship winner, gold medalist at the 2015 Kontiolahti in mixed relay and gold medalist at 2017 Hochfilzen in 7.5 km sprint. In the 2015/2016 World Cup season she was overall champion, and she has also taken six discipline Crystal Globes: the 2013/2014 individual title, the 2015/2016 sprint, pursuit and mass-start titles, and the 2016/17 sprint and mass start titles.
Koukalová began her biathlon career in 2005. In 2007 Koukalová became a member of the national team, and in 2008 she took part in the Biathlon Junior World Championship. Her first experience at the international level was not very good: Koukalová's shooting accuracy and ski speed were at that time not as strong as many of her peers, and her best result at the 2008 Junior Worlds was a 22nd place. Nevertheless, her coaches gave her a chance to take part in further international competitions, including the IBU Cup in the 2008/09 season. Her performances improved: Koukalová, despite some difficulties in shooting, became better than Olga Vilukhina and helped the Czech women's relay team to win a gold at the 2009 Junior World Championships.
