Marko Daňo (born 30 November 1994) is an Austrian-born Slovak professional ice hockey right winger for HC Oceláři Třinec of the Czech Extraliga (ELH).

[4][5] He played eight games with Columbus to begin the 2014–15 season before being assigned to the Springfield Falcons, the Blue Jackets' American Hockey League (AHL) affiliate.

On 30 June 2015, Daňo, along with Jeremy Morin, Artem Anisimov and Corey Tropp, were traded to the Chicago Blackhawks in exchange for Brandon Saad, Alex Broadhurst and Michael Paliotta.

[8] After attending the Blackhawks training camp in preparation for the 2015–16 season, Daňo as a key piece in the Saad trade was surprisingly reassigned to AHL affiliate, the Rockford IceHogs to begin the year and continue his development.

On 25 February 2016, Daňo and the Blackhawks' first-round pick in the 2016 NHL Entry Draft was traded to the Winnipeg Jets in exchange for Andrew Ladd, Jay Harrison and Matt Fraser.

After failing to receive a qualifying offer for the second consecutive season, Daňo remained in Europe, returning to his original hometown club, HK Dukla Trenčín of the Tipsport Liga, signing a contract with an NHL-out clause on 4 October 2020.

[20] Unable to add to his NHL experience with the Jets, Daňo was assigned to the AHL and played in 13 games throughout the 2020–21 season with the Manitoba Moose.

As a free agent in the off-season, Daňo returned to Europe by signing an initial two-month contract with the option of a one-year deal with Czech-based club HC Oceláři Třinec of the ELH on 6 September 2021.
