* Domain: Eukarya (organisms with a nucleus)
* Kingdom: Animalia (multicellular organisms that are heterotrophic)
* Phylum: Chordata (animals with a notochord)
* Class: Mammalia (animals that have mammary glands and fur/hair)
* Order: Primates (animals with grasping hands and feet)

So, while there is no "kingdom of humans", we do belong to the kingdom Animalia, which includes all animals.
It is important to note that "kingdom" can also be used in a metaphorical sense, such as "the kingdom of England" or "the kingdom of heaven". However, in a biological context, it refers to a specific taxonomic rank within the Linnaean hierarchy.
