Olli Määttä Bio
Olli Määttä is a Finnish professional ice hockey player who plays as a defenceman in the National Hockey League (NHL). Born on 22 August 1994 in Jyväskylä, Finland, Määttä has built a reputation as a dependable two-way blue-liner known for his shot-blocking ability and high hockey IQ. He was selected 22nd overall by the Pittsburgh Penguins in the 2012 NHL Entry Draft and has since represented Finland at the Olympic Games and other major international tournaments. Across his career, he has suited up for several NHL organizations and remains an active contributor on the blue line.
Early Life and Background
Olli Määttä was born and raised in Jyväskylä, Finland, the same city where he first laced up his skates. He began playing hockey in 2000 at a young age after telling his parents that all of the other kids were allowed to play. Määttä grew up with two older brothers, Antti and Eero, in a hockey-friendly household that encouraged his early development. Standing 6 feet 2 inches tall and weighing around 206 pounds, he would eventually develop the frame needed to thrive as an NHL defenceman.
Määttä began his junior career with his hometown club JYP, working his way through the under-16, under-18, and under-20 programs. As a 14-year-old, he appeared in a single game for JYP’s U16 side in the Jr. C SM-sarja classification, and the following year he scored 19 points in seven games. He steadily rose through the Finnish junior ranks, eventually earning a call-up to JYP’s under-20 team in the Jr. A SM-Liiga, where he helped the squad avoid relegation. Alongside his club duties, Määttä represented Finland on the national under-16 and under-18 teams, posting 13 points in 13 international games at the U16 level.
Path to Professional Hockey
After establishing himself in Finland’s junior leagues, Määttä was selected 85th overall by SKA Saint Petersburg in the 2011 KHL Draft, then chosen first overall by the London Knights in the 2011 CHL Import Draft two months later. He accepted London’s invitation and crossed the Atlantic to begin his Ontario Hockey League (OHL) career in the autumn of 2011. In his first OHL season with London, Määttä posted 32 points in 58 games and helped lead the Knights to the J. Ross Robertson Cup as OHL champions, adding 23 points in 19 playoff games.
Määttä played for Finland at three consecutive IIHF World Junior Championships between 2011 and 2013, becoming the youngest Finnish player ever to suit up in the under-20 tournament in 2011. In 2012, he suffered a concussion in the tournament opener against Canada and missed the remainder of the event. He was ranked the eighth-best North American skater ahead of the 2012 NHL Entry Draft, where the host Pittsburgh Penguins selected him 22nd overall in the first round.
Olli Määttä Career
Junior Career (2011–2013)
Määttä joined a London Knights team built to contend for the J. Ross Robertson Cup, and the Knights delivered by posting the OHL’s best regular-season record at 49–18–0–1. Määttä paced the team’s defencemen in scoring with 32 points in 58 games despite missing six games for the 2012 World Juniors. He tied for the team lead in playoff scoring with 23 points in 19 games as London captured its first OHL title since 2004–05, only to fall in overtime to the Shawinigan Cataractes in the 2012 Memorial Cup final.
The following season, London again finished first overall, and Määttä helped lead the Knights to a second consecutive OHL championship, defeating the Barrie Colts in seven games. After the season, Määttä earned an NHL roster spot with Pittsburgh following a strong training camp, buoyed by an injury to veteran defenceman Kris Letang.
Pittsburgh Penguins Era (2013–2019)
Määttä made his NHL debut at the start of the 2013–14 season and quickly established himself as a reliable young defenceman. He recorded his first NHL points on 8 October 2013, assisting on two Jussi Jokinen goals in a 5–2 win over the Carolina Hurricanes, then scored his first NHL goal against Roberto Luongo on 19 October. As Pittsburgh battled injuries on the back end, Määttä’s average ice time climbed above 21 minutes per game in December, and he scored his first multi-goal game on 6 March 2014 against the San Jose Sharks.
On 27 October 2014, the Penguins announced that Määttä would undergo surgery to remove a tumor from his neck that could be a low-grade thyroid cancer. He returned to the lineup just two weeks later but reinjured his shoulder and missed the remainder of the 2014–15 season. Despite the setbacks, Määttä won the Stanley Cup with Pittsburgh in the 2016 playoffs. He played his 300th career NHL game on 1 April 2018 and tied his career high with 29 points during the 2017–18 season, appearing in all 82 games.
Chicago Blackhawks and Los Angeles Kings (2019–2022)
On 15 June 2019, Määttä was traded to the Chicago Blackhawks in exchange for Dominik Kahun and a fifth-round pick. He tallied four goals and 17 points in 65 games during the 2019–20 season while averaging 18:25 of ice time, and he led the team with a plus-seven rating through nine playoff games. On 4 October 2020, he was traded to the Los Angeles Kings in exchange for Brad Morrison, where he spent two seasons on the West Coast.
Detroit Red Wings Era (2022–2024)
On 13 July 2022, Määttä signed a one-year, $2.25 million contract with the Detroit Red Wings as an unrestricted free agent. He quickly became a steady presence on Detroit’s blue line and signed a two-year, $6 million contract extension on 16 February 2023. Entering the 2024–25 season, the final year of that deal, Määttä opened in a third-pairing role and was scoreless through seven games before being on the move again.
Utah and Calgary Flames Era (2024–Present)
With the Utah Hockey Club dealing with injuries on the back end to start their inaugural season, Määttä was traded from Detroit to Utah on 29 October 2024 in exchange for a third-round pick in 2025. He provided veteran stability for the new franchise. During the 2025–26 season, in his second year with Utah (now rebranded as the Mammoth), Määttä was traded alongside Jonathan Castagna and three second-round picks in 2026 to the Calgary Flames in exchange for MacKenzie Weegar on 4 March 2026.
Driving Style and Strengths
Määttä is widely regarded as a defensive-minded blue-liner whose shot-blocking and hockey IQ set him apart. He excels in a shutdown role, using his 6-foot-2 frame and active stick to disrupt opposing cycles and clear the front of the net. Coaches have consistently trusted him in penalty-kill situations and on matchups against top opposing forwards.
Notable Events and Milestones
Highlights of Määttä’s career include winning the Stanley Cup with Pittsburgh in 2016, playing his 300th NHL game in 2018, and being part of Finland’s bronze-medal performance at the 2014 Sochi Winter Olympics. His comeback from neck-tumor surgery in November 2014 and his role on multiple playoff rosters underline his reputation for resilience and consistency.

Stanley Cup and International Highlights
Määttä lifted the Stanley Cup with the Pittsburgh Penguins following the 2016 playoffs, contributing on the back end during their championship run. Internationally, he helped Finland capture bronze at the 2014 Winter Olympics, scoring five points in six games and netting the final goal in a 5–0 victory over the United States in the bronze-medal game. In 2021, he represented Finland at the IIHF World Championship, where the team narrowly lost to Canada in the gold-medal final.
Other Performances

Olli Määttä Family
Family Background and Hockey Roots
Olli Määttä grew up in Jyväskylä, Finland, in a household where hockey was a normal part of childhood. He has two older brothers, Antti and Eero, who also played the sport and helped shape his early interest in the game. The family’s support was central to his development, with his parents encouraging him to start organized hockey in 2000 after he told them that all the other kids were already playing.
Personal Life
Määttä has kept much of his personal life out of the public eye. He was raised in Jyväskylä and remains closely tied to his Finnish roots and his family, including his two older brothers. Details about a spouse or children have not been publicly confirmed.
2025 Season Performance
Olli Määttä entered the 2025 calendar year still with the Detroit Red Wings before being dealt to the Utah Hockey Club on 29 October 2024 in exchange for a third-round pick in 2025. The move gave Utah a steady veteran presence as the franchise launched its inaugural NHL season, with Määttä logging shutdown minutes and contributing on the penalty kill. Utah rebranded as the Utah Mammoth during the 2025–26 season, with Määttä serving as one of the team’s most experienced defencemen before his trade to Calgary on 4 March 2026.
Throughout 2025, Määttä provided the kind of reliable, low-maintenance play that has defined his career. He continued to lean on his shot-blocking and defensive positioning rather than offensive production, serving as a mentor for younger blue-liners on a rebuilding roster. His veteran presence helped stabilize a blueline that had been thinned by injuries early in Utah’s first year.
Looking ahead, Määttä joined the Calgary Flames at the 2025–26 trade deadline as part of a package built around Jonathan Castagna and three second-round picks, with MacKenzie Weegar heading the other way. His role in Calgary is expected to mirror his work in Utah and Detroit, anchoring a third pairing and logging heavy penalty-kill minutes. With the Flames in transition, Määttä’s experience and steady two-way game should keep him in the NHL lineup as the organization continues its rebuild.
