Len Howard (1894-1973) was a British naturalist and musician best known for her studies of birds, published as Birds as Individuals (1952) and Living with Birds (1956).

In her early life, Howard pursued a career in music in London, giving music lessons, organising concerts for the children of the poor and playing the viola professionally in an orchestra under Malcolm Sargent. In 1938, she purchased a plot of land outside the village of Ditchling, Sussex, and built the house she called Bird Cottage. There she developed an intimate and unusual relationship with the wild birds in the area, providing food (including her own war rations), chasing away predators, tending to damaged nests, and allowing the birds to fly and roost throughout her home. Her musical training gave her a unique insight into the diverse character of birdsong. Howard died at Bird Cottage in 1973.
