Contextuality and nonlocality are two fundamental but surprising properties of nature.  Some years ago, Lucien Hardy provided a proof of nonlocality that is widely considered the simplest such proof.  After first explaining the meanings of the terms “contextuality” and “nonlocality,” I show in this talk that there is a simple, Hardy-like proof of contextuality and that it reveals an interesting connection between earlier results on the subject.
