Abom is a nearly extinct language spoken in the Western Province of Papua New Guinea.

Abom is spoken in Lewada (8°20′07″S 142°46′50″E / 8.335225°S 142.780449°E / -8.335225; 142.780449 (Lewada)), Mutam (8°25′30″S 142°55′49″E / 8.424996°S 142.930364°E / -8.424996; 142.930364 (Mutam)), and Tewara (8°22′27″S 142°27′23″E / 8.374194°S 142.45638°E / -8.374194; 142.45638 (Dewala)) villages of Gogodala Rural LLG.

Pawley and Hammarström (2018) classify Abom as a divergent Tirio language on the basis of morphological evidence; Abom shares the same gender ablaut pattern as other Tirio languages.

[3] Evans (2018), however, lists Abom as a separate branch of Trans-New Guinea.

[5] Part of the problem lies in the fact that many recorded Abom words are loans from the Inland Gulf languages, reducing the material needed for comparison.
