List of mammals of Luxembourg
This list shows the IUCN Red List status of the 46 mammal species occurring in Luxembourg. Three of them are near threatened and most are least concern.
The following tags are used to highlight each species' status on the respective IUCN Red List published by the International Union for Conservation of Nature:
| EX | Extinct | No reasonable doubt that the last individual has died. |
| EW | Extinct in the wild | Known only to survive in captivity or as a naturalized populations well outside its previous range. |
| CR | Critically endangered | The species is in imminent risk of extinction in the wild. |
| EN | Endangered | The species is facing an extremely high risk of extinction in the wild. |
| VU | Vulnerable | The species is facing a high risk of extinction in the wild. |
| NT | Near threatened | The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future. |
| LC | Least concern | There are no current identifiable risks to the species. |
| DD | Data deficient | There is inadequate information to make an assessment of the risks to this species. |
Order: [Rodent]ia (rodents)

Order: [Lagomorpha] (lagomorphs)
The lagomorphs comprise two families, Leporidae, and Ochotonidae. Though they can resemble rodents, and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.- Family: Leporidae

- **European rabbit, O. cuniculus introduced
Order: [Eulipotyphla] (hedgehogs, gymnures, shrews, moles, and solenodons)
The order Eulipotyphla contains 4 extant families. The hedgehogs are easily recognised by their spines while gymnures look more like large rats. The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers.- Family: Erinaceidae
- *Subfamily: Erinaceinae
