Lilium regale, called the regal lily, royal lily, king's lily, or, in New Zealand, the Christmas lily, is a species of plant in the lily family, with trumpet-shaped flowers. It is popular in many areas around the world as an ornamental.

Lilium regale is a long-lived, stem-rooting bulbous plant. The leaves are borne at irregular intervals on the stem. Plants grow up to 2 meters high, though 1.2 to 1.5 meters is more common in the garden. The flowers are 14 cm long, funnel or trumpet shaped, white with yellow throat, flushed purple outside. Stamens are prominent. The flowers are strongly especially at night.

The Royal Horticultural Society has given Lilium regale its Award of Garden Merit. It is among the easiest lilies to grow in most temperate climate gardens. It tolerates most soils, except ones prone to waterlogging. It may naturalise in suitable conditions. It can also be grown in large containers. The bulbs are very hardy. Plants can be raised from seed, and grow quickly. Stems may require staking to support the large blooms.
