Margaret Alice Kennard (September 25, 1899—December 12, 1975) was a neurologist who principally studied the effects of neurological damage on primates. Her work led to the creation of the Kennard Principle, which posits a negative linear relationship between age of a brain lesion and the outcome expectancy: in other words, that the earlier in life a brain lesion occurs, the more likely it is for some compensation mechanism to reverse at least some of the lesion's bad effects.

The observation that young brains reorganize more effectively than adult brains was first articulated by Kennard in 1936. Consequently, the notion that how well a brain can reorganize itself after damage as a function of the developmental stage is now known as the "Kennard principle". This research led to one of the earliest experimental evidence for age effects on neuroplasticity.
She worked closely with John Fulton in her famous infant brain studies.
