Enniatins are a class of organic chemical compounds found in Fusarium fungi. They appear in nature as mixtures of cyclic depsipeptides. The main variants are enniatin A, A1, B and B1 together with minor amounts of enniatin C, D, E and F.

The enniatins act as ionophores that bind ammonium,^[1] and they have been proposed as replacements for nonactin in specific ammonium-based electrodes.

Enniatins have been also mentioned as potential anti-AIDS drugs.^{[citation needed]}
