贝母属（学名：Fritillaria）是百合科下的一个属，为多年生草本植物，又名莔（音“虻”）。该属共有85种，分布于北温带。

Fritillaria is a genus of Eurasian, North African, and North American plants in the lily family.

There are about 100 to 130 species of bulbous plants in the family Liliaceae, native to temperate regions of the Northern Hemisphere, especially the Mediterranean, southwest Asia, and western North America. The name is derived from the Latin term for a dice-box (fritillus), and probably refers to the checkered pattern of the flowers of many species. Plants of the genus are known in English as fritillaries. Some North American species are called mission bells.
