The Globidensini or Globidentatini are a tribe of mosasaurine mosasaurs, a diverse group of Late Cretaceous marine squamates. Members of the tribe, known as "globidensins" or "globidensine mosasaurs", have been recovered from North America, Europe, Africa and Asia. The tribe contains the genera Globidens (the best studied genus by far), Carinodens, Igdamanosaurus, Harranasaurus and Xenodens. Features of the maxilla and digits make the placement of Carinodens and Xenodens in the tribe uncertain; some researchers have suggested that they may be more appropriately placed in the Mosasaurini.

Towards the end of the Cretaceous, a series of adaptations allowed the highly specialized mosasaurs within the Globidensini, characterized by knob-like teeth, to successfully reclaim the niche of the durophagous lifestyle. This niche had been unoccupied for most of the Mesozoic ever since the extinction of the placodonts and the durophagous ichthyosaur Grippia. The rarity of the Globidensini in the fossil record remains a mystery, perhaps it is due to habitat preference (deep water), some other form of taphonomic bias or due to the durophagous lifestyle not allowing the establishment of large populations in the first place. In Angola, the disappearance coincides with the extinction of Inoceramus shells.
