Titanosuchidae is an extinct family of dinocephalians known only from the middle Permian Tapinocephalus Assemblage Zone of South Africa.

[2] The titanosuchids were large, omnivorous[3] or herbivorous[2] animals.

As with other tapinocephalians, they had thickened skulls that may have been used in head-butting, but to a lesser degree than in Tapinocephalidae or Anteosauridae.

They had large canine teeth, strong incisors with a "talon and heel" morphology, and leaf-shaped postcanine teeth.

Two titanosuchid genera are recognized as valid: Jonkeria and Titanosuchus; they can be distinguished on the basis of limb proportions.
