In 2019, Malafaia and her team classified Vallibonavenatrix within the Spinosauridae, a family of large-bodied tetanuran dinosaurs traditionally separated into two subfamilies: Spinosaurinae and Baryonychinae.
Though closer in proximity to European baryonychines such as Baryonyx from the Barremian of Spain and England, Vallibonavenatrix was found to be more closely related to spinosaurines such as Spinosaurus and Irritator from the southern supercontinent Gondwana, and the Asian genus Ichthyovenator.
Thus, Malafaia and colleagues placed it within Spinosaurinae, the results of their analysis are shown in the following cladogram:
