Arum is a genus of flowering plants in the family Araceae, native to Europe, northern Africa, and western and central Asia, with the highest species diversity in the Mediterranean region.[1][2] Frequently called "arum lilies", they are not closely related to the true lilies Lilium. Plants in closely related Zantedeschia are also called "arum lilies".

They are rhizomatous, herbaceous perennial plants growing to 20–60 cm tall, with sagittate (arrowhead-shaped) leaves 10–55 cm long. The flowers are produced in a spadix, surrounded by a 10– to 40-cm-long, coloured spathe, which may be white, yellow, brown, or purple; some species are scented, others not. The fruit is a cluster of bright orange or red berries.

All parts of the plants including the berries are poisonous,[3] containing significant amounts of calcium oxalate as raphides.

The genus name is the Latinized form of the Greek name for these plants, aron.
