Erythronium grandiflorum is a species of flowering plant in the lily family. It is known by several common names, including yellow avalanche lily, glacier lily, and dogtooth fawn lily.

It is native to western North America from to British Columbia and Alberta south to New Mexico and California, though it has not been reported from Arizona or Nevada. It can be found in subalpine mountain meadows, slopes, and clearings.[2]

Erythronium grandiflorum grows from a deep bulb which is 3 to 5 centimeters wide. Its two green leaves are wavy-edged and up to 20 centimeters long. The stalk may reach 30 centimeters tall and bears one to three showy flowers. Each flower has bright lemon yellow tepals, white stamens with large white to yellow to red anthers, and a white style. The flower is pollinated by bumblebees and other bees. The bulbs are an important and preferred food of the grizzly bear. Mule deer readily eat the foliage.[3][4][5]

The Ktunaxa name for glacier lily is maxa.[6]
