Iani (after Ianus) is an extinct genus of rhabdodontomorph iguanodontian dinosaur from the Late Cretaceous Cedar Mountain Formation of Utah, United States.

[1] The Iani holotype specimen, NCSM 29373, was discovered in 2014 in sediments of the Cedar Mountain Formation (lower Mussentuchit Member) in Emery County, Utah, United States.

[1] In 2023, Zanno et al. described Iani smithi as a new genus and species of rhabdodontomorph iguanodontian based on these fossil remains.

The generic name, "Iani", alludes to Ianus, the Roman god of transitions, referencing the changing biota of the time.
