Johan Niklas Edin is a Swedish curler. He currently resides in Karlstad, which has been his curling home base since 2008. He holds several sport distinctions. He is the first and the only skip in World Curling Federation (WCF) history to win three Olympic medals – gold (2022), silver (2018), and bronze (2014) – and to skip men's curling teams to seven World Men's Curling Championship medals. He is also a seven-time European Curling Championship titleholder and won three silver medals in those championships. He is currently tied with Oskar Eriksson in first place on the WCF-recognized list of championship medals, with thirty-eight in total. He reached the playoffs in forty-five Grand Slam of Curling events and won the Pinty's Cup with his current teammates, Oskar Eriksson, Rasmus Wranå, and Christopher Sundgren. With the same lineup in 2022, Edin and his teammates also became the first and only men's curling team to win a fourth consecutive World Men's Curling Championship. Edin has played exclusively in the position of skip since 2007. The team bearing his name has been ranked on the World Curling Tour as high as No. 1, including for most of the 2017–18 season. As of the end of the 2021–22 Curling Season, Team Edin was ranked in the top three teams in the world.
