Aleksi Heponiemi (born 9 January 1999) is a Finnish professional ice hockey forward currently playing for EHC Biel in the National League (NL), with his National Hockey League (NHL) rights held by Florida Panthers.

[3] Due to his point-producing skill in his rookie season in the WHL, some think Heponiemi was a steal because of how late he was selected in the second round by the Panthers.

[8] With the 2020–21 North American season delayed until November due to the COVID-19 pandemic, Heponiemi was loaned by the Panthers to Swedish second-tier club, Modo Hockey of the Allsvenskan, on 9 August 2020.

[9] Heponiemi made his NHL debut on 30 January 2021, scoring an overtime goal in the Panthers' 3–2 win over the Detroit Red Wings.

Heponiemi subsequently secured a one-year contract with Swiss club EHC Biel-Bienne of the NL on 21 July 2023.
