Playing career

Djurgårdens IF Landeskog began his youth career in hockey playing for Hammarby IF. After a successful season for Djurgårdens IF in the J20 SuperElit, Landeskog debuted in Elitserien on 21 February 2009, in a game against Brynäs IF, which Djurgårdens IF lost 4–2. At 16 years and 90 days he became the youngest player in Djurgårdens IF's history, and one of the youngest to ever have played in Elitserien. He recorded his first point in Elitserien on 24 February, in his second game, a 2–2 tie against Skellefteå AIK.

Kitchener Rangers

Landeskog was initially drafted in the first round, third overall, by the Plymouth Whalers of the Ontario Hockey League (OHL) in the 2009 CHL Import Draft. However, he never played for the team as his CHL rights were traded to the Kitchener Rangers on 3 August 2009.

By the end of the 2009–10 season, Landeskog was third among OHL rookies in points (trailing Matt Puempel and Boone Jenner) and goals (trailing Puempel and Ivan Telegin). In the playoffs, Kitchener made it to the conference finals where they were eliminated by Windsor, and Landeskog was third overall on his team as well as the highest scoring rookie ahead of teammate Ryan Murphy.

On 24 October 2010 Landeskog was named captain of the Kitchener Rangers for the 2010–11 season. This announcement made him the first European captain in franchise history. During his final season before NHL draft eligibility, despite suffering an ankle injury which shortened his campaign to 53 regular season games, he led all Rangers with 37 goals and a plus-minus of 27. During the playoffs, Landeskog posted a team-high 10 points in a seven-game first-round series defeat to the Plymouth Whalers to end his junior career.

Colorado Avalanche 2011–2012: Rookie season, Calder Trophy

Landeskog was drafted second overall by the Colorado Avalanche in the 2011 NHL entry draft, behind Red Deer center Ryan Nugent-Hopkins. Upon being drafted, Landeskog tied Daniel Sedin and Victor Hedman as the third-highest Swedish draft pick in history. A few days later, the Kitchener Rangers dropped Landeskog from their roster in anticipation of him making the Avalanche out of training camp. As OHL teams were only allowed a small number of European players on their roster, they dropped him to open up space to draft a new player in the OHL import draft. After attending the Avalanche's training camp, Landeskog signed a three-year, entry-level contract with the Avalanche that carried a base salary of $925,000 and an additional $850,000 signing bonus. Landeskog made his NHL debut on 8 October in the Avalanche's opening-night game against the Detroit Red Wings. He finished with five shots on net through 16:03 minutes of ice time while playing on a line with Ryan O’Reilly and Daniel Winnik. Upon making his debut, he become became the first player in Avalanche franchise history to wear jersey number 92, a choice he made in honour of his birth year. While playing with O'Reilly and Winnik, Landeskog scored his first NHL goal on 12 October 2011, against the Columbus Blue Jackets. At 18 years and 324 days, he surpassed Victor Hedman to become the youngest Swedish-born player to score an NHL goal. Later that month, Landeskog recorded his first multi-goal game in a 5–4 shootout win over the Chicago Blackhawks. However, his production remained inconsistent until late December as he grew more confident in his abilities and acclimated to the NHL level. By mid-January, Landeskog had recorded nine goals and 22 points through his first 48 games.

As a result of his efforts, Landeskog was named to Team Chara at the 2012 National Hockey League All-Star Game. After tallying only three points at the start of February, Landeskog recorded five goals and five assists through a six-game point streak to end the month as the league's leading rookie. As such, he was recognized as the NHL's Rookie of the Month. He continued his scoring streak into March and tallied goals in two of the Avalanche's three game road trip against Buffalo, New Jersey, and the New York Rangers. On 12 March 2012, Landeskog recorded his first overtime goal and his 233rd shot on net to break Peter Šťastný's franchise record for most shots on goal in a player's rookie season. Landeskog finished his rookie season leading all rookies with 22 goals and tied Nugent-Hopkins with 52 points. He subsequently became the first Avalanche player since 1999 to win the Calder Memorial Trophy as the NHL's Rookie of the Year. Landeskog was also named to the NHL All-Rookie Team.

2012–2021: Captaincy, continued improvement Following his rookie season, the Avalanche named Landeskog as team captain, at the time making him the youngest captain in NHL history. At 19 years and 286 days, Landeskog was 11 days younger than Sidney Crosby when he was named captain of the Pittsburgh Penguins. However, because of the 2012–13 NHL lockout, he was unable to play a game as captain until 19 January 2013. When the NHL lockout was in effect, Landeskog returned to Sweden to begin the season with Djurgårdens IF. In 17 games with Djurgårdens IF, Landeskog produced six goals for 14 points before returning to North America on 3 December 2012. Once the lockout concluded, Landeskog recorded one goal in four games before suffering a head injury during a game against the San Jose Sharks on 26 January. He missed 11 games to recover before returning to the Avalanche's lineup on 22 February 2013. Landeskog later wrote about his experience with his concussion in a Players' Tribune article and urged younger players to "understand the complexity" and effects of concussions. Due to his injury and the shortened nature of the 2012–13 season, Landeskog was limited to 17 points in 36 games. After the Avalanche were eliminated from playoff contention and the regular season ended, Landeskog represented Sweden senior team at the 2013 World Championship and captured a gold medal. On 15 August 2013, the Avalanche signed Landeskog to a seven-year contract extension worth $39 million.

Landeskog proved to be a significant piece of a resurgent Colorado Avalanche team during the 2013–14 season. He put up career highs in goals, assists, and points, helping the Avalanche to a division title. He scored his first career NHL playoff goal on 17 April 2014, against Ilya Bryzgalov of the Minnesota Wild.

On 3 March 2015, Landeskog was fined $5,000 for punching Mikko Koivu with 3.3 seconds remaining in a game against the Minnesota Wild. Landeskog had been given a misconduct penalty at the time. On 13 November 2015, Landeskog was suspended two game for an illegal check to the head on Boston Bruins forward Brad Marchand. On 10 March 2016, Landeskog was suspended for three games without pay due to him cross-checking Simon Després in the neck area with his stick during a game. While he had not been penalized for the play at the time, the Department of Player Safety determined it was a punishable offence upon review.

Landeskog began the 2016–17 season tied for second on the team in points while playing with his usual linemates, Nathan MacKinnon and Mikko Rantanen. However, after scoring an empty-net goal against the Los Angeles Kings on 15 November, Landeskog suffered a lower body injury and was placed on the team's injured reserve list. He missed 10 games to recover from the injury and returned to the Avalanche's lineup on 10 November for their game against the Montreal Canadiens. Landeskog finished the 2016-17 regular season with 18 goals and 15 assists through 72 games and was named to Team Sweden's roster for the 2017 IIHF World Championship. Despite his efforts, the Avalanche finished the season with the franchise’s worst record since moving to Denver.

Landeskog recorded his first career hat trick in a 6–2 win over the Washington Capitals on 17 November 2017. A few weeks later, Landeskog was suspended for four games and forfeited $119,815.68 in salary for cross-checking Matthew Tkachuk during a game. He recorded his second career hat trick on 16 December 2017 in a 6–5 loss to the Tampa Bay Lightning. Landeskog played in his 500th career NHL game on 26 March 2018 in a 4-1 loss against the Vegas Golden Knights. The Avalanche qualified for the 2018 Stanley Cup playoffs but lost to the Nashville Predators in six games.

Landeskog recorded his third career hat trick in a 5–3 win over the New Jersey Devils on 18 October 2018. He ended the week leading the NHL in goals and was selected as the NHL's First Star of the Week. He was later one of three Avalanche players who were selected to participate in the 2019 NHL All-Star Game. It was the first NHL All-Star Game of his career. Landeskog finished the 2018–19 NHL season with a career-high 34 goals and 41 assists.

Landeskog was recognized as the NHL's Second Star of the Week on 2 March after recording nine points over four games. In the following week, Landeskog tallied his 20th goal of the season to pass Peter Forsberg and Paul Stastny on the Avalanche's all-time list for most 20 goals seasons. In game six of the 2020 Stanley Cup playoffs, Cale Makar's skate blade accidentally cut Landeskog's knee. After medical evaluation, he skated one 16-second shift in the third period but was unable to play out the remainder of the game. The cut resulted in a cartilage injury on the bottom of his patella.

On 16 January 2021, Landeskog scored his 200th career NHL goal to help lift the team to an 8–0 win over the St. Louis Blues. On 4 February, Landeskog entered the NHL's COVID-19 protocols and the team's contest against the Minnesota Wild was postponed due to numerous other players also being unavailable. He missed over two weeks to recover and played on the third line in his first game back on 21 February against the Vegas Golden Knights.
