Bombyx mori, the domestic silkmoth, is an insect from the moth family Bombycidae. It is the closest relative of Bombyx mandarina, the wild silkmoth. The silkworm is the larva or caterpillar of a silkmoth. It is an economically important insect, being a primary producer of silk. A silkworm's preferred food is white mulberry leaves, though they may eat other mulberry species and even Osage orange. Domestic silkmoths are closely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silkmoths are different from their domestic cousins as they have not been selectively bred; they are thus not as commercially viable in the production of silk.

Sericulture, the practice of breeding silkworms for the production of raw silk, has been under way for at least 5,000 years in China, whence it spread to India, Korea, Japan, and the West. The domestic silkmoth was domesticated from the wild silkmoth Bombyx mandarina, which has a range from northern India to northern China, Korea, Japan, and the far eastern regions of Russia. The domestic silkmoth derives from Chinese rather than Japanese or Korean stock.

Silkmoths were unlikely to have been domestically bred before the Neolithic Age. Before then, the tools to manufacture quantities of silk thread had not been developed. The domesticated B. mori and the wild B. mandarina can still breed and sometimes produce hybrids.

Domestic silkmoths are very different from most members in the genus Bombyx; not only have they lost the ability to fly, but their color pigments have also been lost.
