Shelford's Law of Tolerance, also known as the "Principle of Tolerance," is a concept in ecology that states that the distribution and abundance of a species is determined by the limits of its tolerance to environmental factors such as temperature, moisture, light, and nutrients. This law was first proposed by American ecologist Victor Shelford in 1913.

The law states that the range of environmental conditions that a species can tolerate will determine its geographical distribution and abundance. At the lower limit of a species' tolerance, it is unable to survive, while at the upper limit, it is unable to reproduce or grow. The range between the upper and lower limits of a species' tolerance is referred to as its "ecological amplitude."
