Didymocheton mollis is a species of flowering plant in the family Meliaceae.

It is a tree native to Sulawesi, the Maluku Islands, New Guinea, and the Bismarck Archipelago.

[1] It is most closely related to Didymocheton mollissimus of Malesia and mainland Southeast Asia, D. alliaceus of the Solomon Islands and western Pacific Islands, and D. muelleri of northeastern Australia.

[2] The species was first described as Dysoxylum molle by Friedrich Anton Wilhelm Miquel in 1868, from a holotype collected in southwestern New Guinea.

A 2021 study by Holzmeyer, Hauenschild, Mabberley, et al. concluded that Dysoxylum was polyphyletic, and that the Australian population constituted a distinct species from the northern population.
