The Uintan North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 46,200,000 to 42,000,000 years BP lasting .
The Uintan is considered to be contained within the Lutetian sharing the upper boundary and contains the following substages:
- Late/Upper Uintan. Lower boundary source of the base of the Uintan (approximate).
- Early/Lower Uintan. Upper boundary source of the base of the Duchesnean (approximate)
