Crocus flavus, known as yellow crocus or Dutch yellow crocus, is a species of flowering plant of the Crocus genus in the Iridaceae family. It grows wild on the slopes of Greece, former Yugoslavia, Bulgaria, Romania and northwestern Turkey, with fragrant bright orange-yellow flowers which Tennyson likened to a fire. It is a small crocus (5–6 cm (2–2 in), despite the names of some cultivars, compared to the Giant Dutch crocuses (C. vernus). Its cultivars are used as ornamental plants.
C. flavus naturalises well in the garden, and its cultivars are used as ornamental plants. The subspecies C. flavus subsp. flavus has gained the Royal Horticultural Society's Award of Garden Merit.
