Gonatus fabricii, the Boreo-atlantic Armhook Squid, is a squid in the family Gonatidae.

It occurs in the northern Atlantic Ocean from Canada to the Barents Sea.

[verification needed] Until 1981, the name G. fabricii was usually misapplied to the very similar relative G. steenstrupi.

G. fabricii grows to 30 cm in mantle length.

[3][verification needed] The type specimen was collected off Greenland and is deposited at the Zoologisk Museum of Kobenhavns Universitet in Copenhagen.
