Eryngium is a genus of flowering plants in the family Apiaceae. There are about 250 species. The genus has a cosmopolitan distribution, with the center of diversity in South America. Common names include eryngo and amethyst sea holly (though the genus is not related to the true hollies, Ilex).

These are annual and perennial herbs with hairless and usually spiny leaves. The dome-shaped umbels of steely blue or white flowers have whorls of spiny basal bracts. Some species are native to rocky and coastal areas, but the majority are grassland plants.

In the language of flowers, they represent admiration.

Species are grown as ornamental plants in gardens. Numerous hybrids have been selected for garden use, of which E. × oliverianum and E. × tripartitum have gained the Royal Horticultural Society's Award of Garden Merit.

Many species of Eryngium have been used as food and medicine. Eryngium campestre is used as a folk medicine in Turkey. Eryngium creticum is a herbal remedy for scorpion stings in Jordan. Eryngium elegans is used in Argentina and Eryngium foetidum in Latin America and South-East Asia. Native American peoples used many species for varied purposes. Cultures worldwide have used Eryngium extracts as anti-inflammatory agents. Eryngium yields an essential oil and contains many kinds of terpenoids, saponins, flavonoids, coumarins, and steroids.
