Yongjinglong was placed in the Titanosauria by Li et al. (
2014).
Their cladistic analysis showed it was a member of the Somphospondyli and a sister species of Opisthocoelicaudia.
However, a 2019 revision of Chinese "titanosaurs" resolved Yongjinglong deeply nested within Euhelopodidae, sister taxon to Huanghetitan and Ruyangosaurus, or a clade including Euhelopus, Erketu and Gobititan.
