Michael John Disney (born Bristol, England, 7 October 1937) is an astrophysicist. He discovered the optical component of the Crab Pulsar in 1969 with John Cocke. This was the first optical pulsar ever observed.
He was also one of the pioneers in the discovery of low surface brightness galaxies.
He was the co-author with Alan Wright of the humorous (and often mis-attributed) short story 'Impure Mathematics'.
