Johansen debuted in the NHL with the Columbus Blue Jackets on Oct. 7, 2011, against the Nashville Predators, and would make history that season: He was the first player in the League to score his team's first three game-winning goals in a season since Brian Propp of the Philadelphia Flyers in 1982-83.

He got his first NHL point with an assist Oct. 22, 2011, against the Ottawa Senators and scored his first NHL goal, a game-winner, Oct. 25, 2011, against Ty Conklin of the Detroit Red Wings. In 2012-13 Johansen led the Blue Jackets in face-off wins with 272 and scored his first NHL shootout goal on March 10 at Detroit.

Johansen was the youngest NHL player to score 30 goals in 2013-14 and joined Rick Nash and Geoff Sanderson as players with 30-goal seasons in Blue Jackets history. The center led Columbus in goals (33), points (63), multipoint games (16), shots on goal (237) and face-off wins (692). Johansen made his Stanley Cup Playoff debut April 16, 2012, and scored his first NHL playoff goal three days later; both came against the Pittsburgh Penguins in the first round.

In 2014-15, Johansen became the fourth player in Blue Jackets history to have 70 points in a season, joining Nick Foligno (2014-15), Nash (2008-09) and Ray Whitney (2002-03). He had an NHL season-best 13-game point streak from Dec. 18, 2014-Jan. 17, 2015. Johansen was named NHL All-Star Game MVP after getting two goals and four points on Jan. 25, 2015, at Nationwide Arena in Columbus.

Traded by Columbus to the Nashville Predators on Jan. 6, 2016, for Seth Jones, Johansen had eight goals and 34 points in 42 games with the Predators in 2015-16. He had a goal and an assist in his Nashville debut Jan. 8, 2016, against the Colorado Avalanche.

Johansen had 13 points (three goals, 10 assists) in 14 Stanley Cup Playoff games for Nashville in the 2017 Stanley Cup Playoffs before being sidelined with a serious leg injury sustained in Game 4 of the Western Conference Final against the Anaheim Ducks. He required surgery and was unable to play during the Cup Final, when the Predators lost to the Pittsburgh Penguins in six games. However, he rebounded with 54 points (15 goals, 39 assists) during the regular season and 14 points (five goals, nine assists) in 14 playoff games.

The Predators traded Johansen to the Colorado Avalanche for Alex Galchenyuk on June 24, 2023. He had surgery on his right leg and missed the final 27 games of the 2022-23 season after he was cut by a skate blade against the Vancouver Canucks on Feb. 21. Colorado then traded him to the Philadelphia Flyers on March 6, 2024.

Johansen was selected by Columbus with the No. 4 pick in the 2010 NHL Draft after scoring 25 goals and 69 points for Portland of the Western Hockey League in 2009-10. He ranked second among WHL rookies in assists (44) and points (69) that season and led rookies with 12 assists and 18 points during the 2009-10 playoffs.

He led Portland with 40 goals and 92 points in 2010-11, and was the league's top playoff scorer with 28 points (13 goals), helping his team reach the league final. Johansen helped Canada finish second at the 2011 IIHF World Junior Championship and was named to the tournament all-star team after scoring three goals and nine points in seven games.
