The Grey-headed Social Weaver was formally described by Charles Lucien Bonaparte, a French biologist and ornithologist. Around 1849 Bonaparte began work on preparing a classification of all the birds in the world, visiting museums across Europe to study the collections. In 1850, he published the first volume of his Conspectus Generum Avium which included 3 weavers. Bonaparte studied the type specimen of the Grey-headed Social Weaver in the Paris Museum. He named it after the French collector Joseph-Pons d'Arnaud, a French engineer, hunter and explorer.

Three expeditions were fitted out between 1839 and 1842 to search for the source of the White Nile. The second trip, with d'Arnaud as the scientific chief of the expedition, reached to around Juba. d'Arnaud collected a variety of birds, including the Grey-headed Social Weaver, which were sent to the Paris Museum.

The first illustration of a Grey-headed Social Weaver is by Heuglin (1871). The next illustration was a line drawing of the bird's wing, published by Sharpe (1890). Reichenbach (1863) mentioned the species, and provided an English name, but did not illustrate it.
