蓝雪属（学名：Plumbago）是蓝雪科下的一个属，为多年生草本或亚灌木植物，有时为藤本植物。该属共有约12种，分布于温带地区。

Plumbago is a genus of 10-20 species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of the world. Common names include plumbago and leadwort (names which are also shared by the genus Ceratostigma). The generic name, derived from the Latin words plumbum ("lead") and agere ("to resemble"), was first used by Pliny the Elder (23-79) for a plant known as μολυβδαινα (molybdaina) to Pedanius Dioscorides (ca. 40-90). This may have referred to its lead-blue flower colour, the ability of the sap to create lead-colored stains on skin, or Pliny's belief that the plant was a cure for lead poisoning.
