The Chenopodiaceae are a family of flowering plants, also called the Goosefoot family. Although widely recognized in most plant classifications (notably the Cronquist system), the more recent gene-based APG system (1998) and the APG II system (2003) have included these plants in the family Amaranthaceae; molecular phylogeny has shown it to be paraphyletic.

However, a leading authority, the Jepson Herbarium, classifies Chenopodiaceae as a separate family from Amaranthaceae, they can be herbaceous or woody, and their flowers are usually in inflorescences of "raceme[s], spike[s], catkin-like, spheric head[s], axillary clusters of flowers."[1] The individual flowers are generally small, green, and leaf-like.[2] Many of Chenopodiaceae are halophytic, and leaves can be covered with small, scale-like, salt-secreting glands.[3] Or the leaves might be succulent, they are found around the world, especially in "deserts, saline or alkaline soils."[4] Some are even cultivated for food, including beet (Beta vulgaris), Swiss chard, spinach (Spinacia oleraceae), and quinoa (Chenopodium quinoa)[5]
