Seed dispersal by ants is a dispersal mechanism by many shrubs of the southern hemisphere or understorey herbs of the northern hemisphere.

Seeds of myrmecochorous plants have a lipid-rich attachment called the elaiosome, which attracts ants. Ants carry such seeds into their colonies, feed the elaiosome to their larvae and discard the otherwise intact seed in an underground chamber.

Myrmecochory is a coevolved mutualistic relationship between plants and seed-disperser ants.
