The Drosophila immigrans species group is a polyphyletic and speciose lineage of Drosophila flies, including over 100 species.

[1][2] Immigrans species belong to the Immigrans-tripunctata radiation of the subgenus Drosophila.

The genome of D. albomicans was sequenced in 2012 in an effort to characterize novel sex chromosome development in D.

[3] Immigrans group species are related to mushroom-breeding Drosophila of the Quinaria and Testacea species groups.

[2][4] The Immigrans species group can be further divided into four subgroups:[2]
