Aphaenogaster donisthorpei is an extinct species of ant in formicid subfamily Myrmicinae known from a Late Eocene fossil from North America.

The insects and plants suggest a climate similar to modern Southeastern North America, with a number of taxa represented that are now found in the subtropics to tropics and confined to the old world.

[3][4][5] At the time of description the holotype specimen, number 2917 was deposited in the Museum of Comparative Zoology paleontology collections at Harvard University.

The etymology for the specific epithet donisthorpei was not specified with the type description, but Horace Donisthorpe (1870–1951) was a British myrmecologist and coleopterist.

[1] The Aphaenogaster donisthorpei specimen is a partially preserved queen caste adult which was fossilized with its dorsal side facing upwards and the attached wings outspread.
