Bruce Mouat (/ˈmaʊət/; born 27 August 1994 in Edinburgh) is a Scottish curler from Stirling. He currently skips his own team out of the Gogar Park Curling Club. Mouat has led his team to two world championship titles in 2023 and 2025, four European championship titles (2018, 2021, 2022 and 2023) and twelve Grand Slam titles. He also earned two silver medals in the men's team event of the Winter Olympics (2022, 2026). He is a former World Mixed Doubles (2021), Winter Universiade (2017) and World Junior (2016) champion.

Mouat had a successful junior career, winning two Scottish junior championships in 2015 and 2016. He skipped the Scottish team at the 2015 World Junior Curling Championships, where he led his team of Duncan Menzies, Derrick Sloan and Angus Dowell to a bronze medal. The team had a 6–3 round robin record, which was good enough for third place. They lost to Sweden in the 3 vs. 4 playoff game but won in a re-match against the Swedes in the bronze medal game. Mouat would again skip Scotland at the 2016 World Junior Curling Championships, this time with teammates Bobby Lammie, Gregor Cannon along with Dowell again. The team posted a 7–2 record through the round robin, finishing second. In the playoffs, they would beat the United States' Korey Dropkin in the 1 vs. 2 game and beat them again in the final to claim the gold medal. The following season, Mouat and his reigning world championship rink represented Great Britain at the 2017 Winter Universiade. Once again, the team was dominant, finishing atop the round robin standings with a perfect 9–0 record. After a narrow victory over Norway in the semifinal, the team won 8–6 against Sweden in the gold medal game.

While still in juniors, Team Mouat began competing on the men's tour. Nationally, the team had a bronze medal finish at the 2015 Scottish Men's Curling Championship and a silver medal finish in 2017. The team won their first tour event at the 2015 Dumfries Challenger Series, defeating previous Scottish champion Tom Brewster in the final. They also reached the semifinals of the Challenge Chateau Cartier de Gatineau following wins over established men's teams such as John Epping, Sven Michel and Rasmus Stjerne. As they had won the 2016 World Juniors, the team was invited to compete in their first Grand Slam of Curling event, the 2016 Humpty's Champions Cup. With wins over Niklas Edin and John Shuster, the team earned a tiebreaker berth where they lost to Steve Laycock. In their final season of juniors, the team qualified for the 2016 Tour Challenge Tier 2 event where they again lost in a tiebreaker to Mark Bice.

Out of juniors, Mouat formed a new rink with Grant Hardie, Bobby Lammie and Hammy McMillan Jr. for the 2017–18 season. On tour, the team found immediate success, going undefeated to claim the Stu Sells Oakville Tankard and the Oakville Fall Classic in back-to-back weeks. In both finals, the team beat the Kim Chang-min Korean rink. Later in the season, the Mouat rink would again beat Kim in another final, this time at the 2017 Boost National, the first Grand Slam event of the season. By winning the event, Mouat captured his first career Grand Slam title and became the youngest skip and only the second-ever non-Canadian skip to win a men's Grand Slam event. The team followed this win with their fourth tour win of the season at the Dumfries Challenger Series back home in Scotland. In the new year, the team ran the table to win the 2018 Scottish Men's Curling Championship, defeating the Greg Drummond rink in the final. They then faced the Kyle Smith Olympic team in a best-of-three playoff to determine who would represent Scotland at the 2018 World Men's Curling Championship. Team Mouat won the series two games to one, earning the right to represent the country at their first men's worlds. In preparation for the world championship, the team won another tour event at the Aberdeen International Curling Championship, defeating Yannick Schwaller in the final. At the world championship in Las Vegas, Nevada, the team lost just one game in the round robin to Sweden's Niklas Edin. Their 11–1 record earned them a direct bye to the semifinals where they suffered a 9–5 defeat to Canada's Brad Gushue. Despite this, they ended the week on a positive note with a dominant victory over Korea's Kim in the bronze medal game. The team ended the season at the 2018 Players' Championship and 2018 Humpty's Champions Cup Slam events where they reached the quarterfinals and semifinals respectively.

Team Mouat's first major bonspiel of the 2018–19 season came in September at the first leg of the Curling World Cup, where the team had a third-place finish. Two weeks later, they played in the 2018 Elite 10 Grand Slam event, where they won just one game. A month later, the team was more successful at the 2018 Masters Grand Slam, making it to the semifinals. A month later, Mouat made his debut at the 2018 European Curling Championships. After finishing the round robin with a 7–2 record, Mouat beat Italy's Joël Retornaz and Sweden's Niklas Edin in the semifinal and final to claim the gold medal. Mouat wrapped up the calendar year with another third-place finish at the second leg of the Curling World Cup and a second-place finish at the 2018 National. The National featured the first all-Scotland Grand Slam final as the Mouat rink faced Team Ross Paterson. The team began 2019 by winning the Mercure Perth Masters, followed by a quarterfinal finish at the 2019 Canadian Open. The team then returned to Scotland to defend their Scottish championship, which they won, sending them to the 2019 World Men's Curling Championship in Lethbridge, Alberta. There, the team had a slow 1–3 start, but they managed to turn things around to qualify with an 8–4 record. They then lost to Canada's Kevin Koe in the first playoff round. To wrap the season up, Mouat lost in a tiebreaker at the 2019 Players' Championship and made it to the semifinals at the 2019 Champions Cup.

The Mouat rink did not have a good start to the 2019–20 season as they failed to qualify as the Scottish representatives for the 2019 European Curling Championships. They found better luck in Grand Slam play, however, making it to the semifinals of the 2019 Masters and the 2019 National and the quarterfinals of the 2020 Canadian Open. The team won just one event on tour, defending their championship at the Mercure Perth Masters. In February, Team Mouat won the Scottish Men's Championship for a third year in a row. The team was set to represent Scotland at the 2020 World Men's Curling Championship on home soil in Glasgow before the event got cancelled due to the COVID-19 pandemic. The Scottish championship would be their last event of the season as both the Players' Championship and the Champions Cup Grand Slam events were also cancelled due to the pandemic.

For much of the 2020–21 season, there was no tour due to the pandemic, but Mouat and his team won a series of domestic challenges put on by the British Curling Association. A "curling bubble" was set up in Calgary, Canada, in the Spring, which hosted several events, including the 2021 World Men's Curling Championship and two slams. Mouat represented Scotland at the 2021 Worlds, leading his team to a 9–4 round robin record. In the playoffs, they beat Canada, and RCF (Russia), making it to the final, where they lost to Sweden, skipped by Niklas Edin. A week later, Team Mouat played in the 2021 Champions Cup in the same bubble, winning the event, defeating Team Brendan Bottcher (who had been Team Canada at the Worlds) to claim their second career Slam title. The team continued their impressive run in the bubble during the next event, the 2021 Players' Championship. They would go through pool play as the only undefeated team on both the men's and women's sides with a 5–0 record, earning the team a bye to the semifinals. They continued their undefeated streak in the playoffs, winning the semis and the finals against Brad Gushue to win their second straight Slam title in just six days.

In October 2021, Mouat was announced by British Curling to be the first British curler to represent the country in both the mixed doubles and men's team disciplines at the Olympics. He and Jennifer Dodds would compete in the mixed doubles event, along with his regular team and fifth Ross Whyte in the men's tournament. Mouat had another stellar season in 2021–22. His team started the year by winning the 2021 Stu Sells Oakville Tankard, and then followed it up with winning the 2021 Masters, their fourth Slam title. The team then made another final at the 2021 National which they lost to the Gushue rink. Next for the team was the 2021 European Curling Championships where the team had another dominant performance, winning all eleven of their games en route to another gold medal. At the Olympics, he led Great Britain to an 8–1 round robin record, in first place overall. In the playoffs, he beat the defending champion John Shuster rink from the United States before losing the gold medal to Sweden, skipped by Niklas Edin. Team Mouat continued their success after the Olympics, winning their second slam of the season at the 2022 Players' Championship. The team was awarded the Pinty's Cup as the season's best Grand Slam team after their win. In their final event, Team Mouat faltered for the first time all season, failing to qualify for the playoffs at the 2022 Champions Cup.
