449 named features carry the IAU descriptor Crater — a circular depression, almost always an impact scar on Mercury, out of 4,787 in the mapped Solar System.
The IAU assigns each feature class on each world a naming theme. Across the 449 craters with a recorded origin, 87 categories appear, led by France.
Every one has its own page, on the surface it sits on.
209 smaller craters are not listed here. The full Mercury gazetteer has every one.
The same descriptor is used on 12 other worlds, for 4,338 more features.
