The following outline is provided as an overview of and topical guide to ants:

Ants – social insects with geniculate (elbowed) antennae and a distinctive node-like structure that forms a slender waist. Ants are of the family Formicidae and evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago, diversifying after the rise of flowering plants. More than 12,500 out of an estimated total of 22,000 species have been classified.
