虎耳草属（学名：Saxifraga）是虎耳草科下的一个属，为多年生或很少一或二年生草本植物。该属共有约370种，分布于北温带。

Saxifraga is the largest genus in the family Saxifragaceae, containing about 440 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word saxifraga means literally "stone-breaker", from Latin saxum ("rock" or "stone") + frangere ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney stones), rather than breaking rocks apart.
