Chenopodium album is a fast-growing weedy annual plant in the genus Chenopodium.

Though cultivated in some regions, the plant is elsewhere considered a weed. Common names include lamb's quarters, melde, goosefoot and fat-hen, though the latter two are also applied to other species of the genus Chenopodium, for which reason it is often distinguished as white goosefoot. It is sometimes also called pigweed, however, pigweed is also a name for a few weeds in the family Amaranthaceae,: it is for example used for the redroot pigweed (Amaranthus albus).
