Gladiolus (from Latin, the diminutive of gladius, a sword) is a genus of perennial cormous flowering plants in the iris family (Iridaceae).

It is sometimes called the 'sword lily', but usually by its generic name (plural gladioli).

The genus occurs in Asia, Mediterranean Europe, South Africa, and tropical Africa. The center of diversity is in the Cape Floristic Region. The genera Acidanthera, Anomalesia, Homoglossum, and Oenostachys, formerly considered distinct, are now included in Gladiolus.
