Alfred Rupert Sheldrake (born 28 June 1942) is an English author and parapsychology researcher. He proposed the concept of morphic resonance, a conjecture which lacks mainstream acceptance and has been criticized as pseudoscience. He has worked as a biochemist at Cambridge University, Harvard scholar, researcher at the Royal Society, and plant physiologist for ICRISAT in India.

Other work by Sheldrake encompasses paranormal subjects such as precognition, empirical research into telepathy, and the psychic staring effect. He has been described as a New Age author.

Sheldrake's morphic resonance posits that "memory is inherent in nature" and that "natural systems ... inherit a collective memory from all previous things of their kind." Sheldrake proposes that it is also responsible for "telepathy-type interconnections between organisms." His advocacy of the idea offers idiosyncratic explanations of standard subjects in biology such as development, inheritance, and memory.

Morphic resonance is not accepted by the scientific community and Sheldrake's proposals relating to it have been widely criticised. Critics cite a lack of evidence for morphic resonance and inconsistencies between its tenets and data from genetics, embryology, neuroscience, and biochemistry. They also express concern that popular attention paid to Sheldrake's books and public appearances undermines the public's understanding of science.
