Marie-Philip Poulin CQ (born March 28, 1991) is a Canadian professional ice hockey centre and captain for the Montreal Victoire of the Professional Women's Hockey League (PWHL). She is also the captain of the Canada women's national ice hockey team. She was named the IIHF Female Player of the Year in 2025.

A three-time Olympic gold medallist and four-time World Champion with the Canadian national team. She scored the game-winning goal in the gold medal games in three out of four of the Olympics in which she competed (2010, 2014 and 2022), for which she was dubbed Captain Clutch by her teammates and the media. Following another game-winning goal at the 2021 IIHF Women's World Championship, she completed an unprecedented "golden goal hat trick" at major international championships. Since 2015 she has served as the captain of Team Canada, leading them to a silver medal at the 2018 Winter Olympics and a gold medal at the 2022 Winter Olympics.

Raised in Beauceville, Quebec, Poulin started her career playing for the Montreal Stars in the now-defunct Canadian Women's Hockey League at the age of 17, while also playing college hockey for the Dawson Blues. She left the team in 2010 to join the Boston Terriers women's hockey team. In 2015, Poulin returned to and captained the Stars, now the Les Canadiennes de Montreal, before joining the Professional Women's Hockey Players Association (PWHPA), a non-profit dedicated to increasing the professionalization of women's hockey, in 2019. The PWHPA's efforts culiminated in the creation of the PWHL, and Poulin played a key role in the negotiation of the collective bargaining agreement. In 2023, at the inception of the PWHL, she signed with PWHL Montreal (later the Montreal Victoire) and became its captain.

While playing with Les Canadiennes, she won the Clarkson Cup twice and was named CWHL MVP three times. She also won the Billie Jean King Most Valuable Player for the PWHL's 2024-25 season. She is the first female hockey player to win the Northern Star Award as Canada's top athlete of the year, and the second to receive the Bobbie Rosenfeld Award as The Canadian Press' female athlete of the year. She is widely considered to be one of the greatest women's hockey players of all time, as well as one of the greatest Canadian hockey players of any gender.

Marie-Philip Poulin was born on March 28, 1991, in Quebec City, Canada, to Robert and Danye Poulin. Poulin has one sibling, her older brother Pier-Alexandre Poulin. She was raised in the city of Beauceville, Quebec. Poulin began figure skating at the age of four, before being inspired by her brother to switch to hockey at age five. In a 2017 interview, Poulin said playing hockey outdoors with her brother during her childhood was one of her best memories of growing up. She first saw professional women's hockey on television during the 2002 Olympic Winter Games, when the Canada women's national ice hockey team won the first gold medal for Canada in ice hockey in more than 50 years.

Poulin spent 2007–08 with the Montreal Stars of the Canadian Women's Hockey League (CWHL). She appeared in only 16 games, but led rookies in scoring with 22 goals and 21 assists. So dominant was she in half a season as a 16-year-old rookie that she finished runner up in the CWHL Most Valuable Player (MVP) vote by club captains. She was also a recipient of the Montreal Canadiens scholarship program in January 2008. For the 2008–09 season, while attending Dawson College, she played both with the Dawson Blues and as an associate player with the Stars. At year's end in March 2009, she helped the Stars win the first Clarkson Cup over the Minnesota Whitecaps in Kingston, Ontario. In the championship game, she assisted on a goal by Caroline Ouellette.

Poulin debuted with the Boston University Terriers women's program during the 2010–11 season. On October 2, 2010, she scored the first goal of her NCAA career in a 5–4 loss at North Dakota. With her third shorthanded goal of the season on October 15, she tied BU's single-season record for shorthanded tallies in just four games. She led all NCAA freshmen in goals (9) and points per game (2.00) during October 2010. In addition, she led all Hockey East freshmen in goals, assists, and points during the month. In the first seven games of her NCAA career, she had a seven-game point-scoring streak consisting of nine goals and seven assists. On December 7 and 10, two wins over Northeastern and Harvard, Poulin registered three goals. In both games, she had a total of 11 shots on goal and a +2 rating. On December 10, she scored two goals and a game-high eight shots as BU prevailed by a 5–3 mark over Harvard.

On January 15 and 16, 2011, Poulin recorded five points (2 goals, 3 assists) in BU's two wins over Boston College and Maine. Against BC, Poulin notched a power-play goal and two assists. Versus the Maine Black Bears, she registered a goal and an assist. On January 22, 2011, Poulin recorded a hat trick, including two power-play goals as BU prevailed over Vermont in a 4–0 win. The win was the Terriers' 100th win in program history. Poulin broke BU's single-season points record with her second goal of the game and later tied the single-season goals record with her third marker. She became the first Terriers player to be honoured as Hockey East Rookie of the Year in March 2011. A fracture of the shoulder did not hold her from action for the 2011–12 season.
