Johan Niklas Edin (born 6 July 1985) is a Swedish curler. 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). He is also the only curler to skip men's curling teams to eight World Men's Curling Championship gold medals (2013, 2015, 2018, 2019, 2021, 2022, 2024, 2026).

Edin is an eight-time European Curling Championship titleholder (2009, 2012, 2014–2017, 2019, 2025) and won four silver medals in those championships (2011, 2018, 2021, 2023). He is currently tied with his teammate Oskar Eriksson in first place on the WCF-recognized list of championship medals, with thirty-eight in total. He reached the playoffs in forty-eight 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. He currently resides in Karlstad, which has been his curling home base since 2008.

Niklas Edin participated in as many as ten different sports simultaneously before he took up curling. He started curling in 1999, inspired in part by the Swedish women's team skipped by Elisabet Gustafson when they secured the bronze medal at the 1998 Winter Olympics. Five years later in 2004, Edin skipped his own team to a World Junior Curling Championship title for Sweden, defeating the team skipped by Stefan Rindlisbacher for Switzerland. The following year, Edin was selected as the alternate for the silver medal-winning Swedish team skipped by Nils Carlsén at the World Junior Curling Championships. Edin also skipped a new team in 2005 to a silver medal at the European Mixed Curling Championships, together with future longtime teammate Sebastian Kraupp. In 2006, Edin won a second silver medal at the World Junior Curling Championships, this time playing third for Team Carlsén. The team also qualified for the 2006 World Men's Curling Championship, finishing in fifth place.

Over the next two years, Edin proved his skills with a variety of teams on an international level. In 2007, Edin skipped a new team, playing this time with his future teammates in the senior division Fredrik Lindberg and Kristian Lindström at the World Junior Championships, winning his third silver junior championship medal. In 2008, Edin also skipped yet another team to the bronze medal at the 2008 European Mixed Curling Championships, with Anna Hasselborg playing third. In 2007 and 2008, Edin joined up with Team Scotland to represent Sweden in the Contintental Cup and was the only participant from Sweden in 2007. As Sweden has participated in the Cup every other year, Edin's 2007 appearance has ensured that Sweden is the only European country to appear in every Continental Cup.

In the spring of 2008, Edin moved to Karlstad along with Sebastian Kraupp, Fredrik Lindberg, and Viktor Kjäll to form a new team, choosing the Karlstad Curling Club as their curling home. Together, the new team filled the void in Swedish men's curling left by the retirement of Peja Lindholm and quickly became seen in Sweden as the team most likely to have success on the international curling circuit. In 2009, Team Edin won Sweden's Elite Series as well as the Swedish National Championship. The team also represented Sweden at the Winter Universiade and won the gold medal. That same season, Team Sweden, led by Mattias Mabergs, finished in 8th place at the 2008 European Curling Championships and fell short in two of three tight games against Finland in the relegation challenge for the 2009 World Men's Curling Championship. No Swedish team, therefore, could compete at the world championships that year.

In the 2009–2010 season, Team Edin was considered the frontrunner for Sweden's national team. In December 2009, the team won the gold medal at the 2009 European Curling Championships, their first appearance at the championship. During the 2010 Elite Series, however, they lost a tough final to their closest rivals, Team Carlsén, by the score of 6–5. Team Carlsén was selected for the 2010 World Men's Curling Championship but underperformed with a 4–7 loss. Team Edin was selected to participate in the 2010 Winter Olympics. They barely missed the medal platform, placing fourth and losing the bronze medal game to Switzerland. They also cemented their status over their closest rivals Team Carlsén by winning the Swedish Curling Championships.

Team Edin's 2010–11 season continued to advance their status as the top team in Sweden by winning Sweden's Elite Series championships. On the World Curling Tour, the team also started strongly by winning the Oslo Cup and making the finals of the Baden Masters. At the 2010 European Curling Championships, the team was unable to secure a playoff spot but made up for this by winning a bronze medal at the 2011 World Men's Curling Championship. On the World Curling Tour, Team Edin also made it to two Grand Slam quarterfinals – the Masters and the National – as well as the Perth Masters semifinals. The team ended their season by becoming the first non-Canadian team to make it to a men's Grand Slam final at the 2011 Players' Championship, losing in the final to Team Kevin Martin.
