  Guilleminea is a small genus of plants in the family Amaranthaceae. They are sometimes known as matweeds. These are prostrate, mat-forming perennial herbs growing from taproots. The best known species is perhaps Guilleminea densa, the small matweed, which is present on most continents and is often a weed. The other species are native to the Americas. The genus was named after the French botanist Jean Baptiste Antoine Guillemin.
