Mikko Kokkonen (born 18 January 2001) is a Finnish professional ice hockey defenceman for Linköping HC of the Swedish Hockey League (SHL). He was selected 84th overall by the Toronto Maple Leafs in the 2019 NHL entry draft.
Kokkonen played as a youth within hometown club, Mikkelin Jukurit, before becoming the youngest player in history to play in the Liiga during the 2016âÂÂ17 season. Following his selection by the Toronto Maple Leafs of the National Hockey League (NHL) in the third-round, 84th overall, in the 2019 NHL Entry Draft, Kokkonen continued his development with Jukurit, appearing in 39 regular season games and collected 3 goals and 10 points in the 2019âÂÂ20 season.
In his fifth year in the Liiga during the 2020âÂÂ21 season, Kokkonen was selected as an alternate captain for Jukurit. He made 50 appearances with Jukurit, adding 1 goal and 10 points. To extend his 2020âÂÂ21 season, Kokkonen agreed to join the Toronto Maple Leafs American Hockey League (AHL) affiliate, the Toronto Marlies, for the remainder of the campaign on 16 April 2021. He played in 11 games with the Marlies, scoring one goal and seven points.
On 15 April 2021, Kokkonen opted to leave his hometown club, furthering his development by agreeing to a two-year contract with fellow Liiga club, the Lahti Pelicans. He played in 58 games for Lahti, registering one goal and 15 points.
On 31 March 2022, the Toronto Maple Leafs announced they had signed Kokkonen to a three-year, entry-level contract, beginning in the season. For the 2022âÂÂ23 season Kokkonen was assigned first to the Marlies, and then to Toronto's ECHL affiliate, the Newfoundland Growlers. Kokkonen attended the Maple Leafs 2023 training camp and was one of the last players the Maple Leafs assigned to the Marlies to start the 2023âÂÂ24 season.
After three seasons within the Maple Leafs organization, having played exclusively with affiliates in the AHL and ECHL, Kokkonen left the club as a free agent and was signed to a one-year deal upon his return to Europe with Swedish club, Linköping HC of the SHL, on 11 August 2025.
Kokkonen represented Finland at two World Junior Championships; the first in 2020 and the second in 2021, winning the bronze medal in the latter. Over 14 games, Kokkonen scored two goals and three points.
He is from the city of Mikkeli.
