|Life restoration of a Euhelopus zdanskyi|
Euhelopodidae is a family of sauropod dinosaurs which includes the genus Euhelopus. The family name was first proposed by American paleontologist Alfred Sherwood Romer in 1956. The four genera Chiayusaurus, Omeisaurus, Tienshanosaurus, and Euhelopus were the original proposed euhelopodines (subfamily Euhelopodinae). Other Chinese genera, such as Mamenchisaurus, used to be placed within this family, but are now in Mamenchisauridae.
Michael D'Emic (2012) formulated the first phylogenetic definition of Euhelopodidae, defining it as the clade containing "neosauropods more closely related to Euhelopus zdanskyi than to Neuquensaurus australis". The phylogenetic analysis conducted by the author indicated that such defined Euhelopodidae, in addition to Euhelopus itself, contained genera Qiaowanlong, Erketu, Daxiatitan, Tangvayosaurus and Phuwiangosaurus as well.
