Finn Adolf Erik Johan Malmgren (9 January 1895 – c. June 1928) was a Swedish meteorologist and Arctic explorer.

From 1922 to 1925, Malmgren participated in the expedition of Roald Amundsen and Harald Ulrik Sverdrup in the Arctic, on board the Maud.

During the third flight, on 25 May, the airship crashed and several members of the expedition were stranded on floating ice, Malmgren with an injured shoulder among them.

On 30 May, Malmgren together with Italian officers Filippo Zappi and Adalberto Mariano, decided to walk back to Kings Bay for help [2].

On 11 July, Soviet pilot Boris Chukhnovsky from the icebreaker Krasin sighted Mariano and Zappi and also Malmgren's body.
