Sir Michael Mann PC (1930–1998) was an English judge who served as a Lord Justice of Appeal from 1988 to 1995.
Mann held one of the senior judicial positions in England and Wales during the late twentieth century. As a Lord Justice of Appeal, he sat in the Court of Appeal, the second-highest court in the English legal system, hearing appeals from lower courts on points of law and fact. He was appointed to the Privy Council, an honour typically granted to senior judges and reflected by the post-nominal letters PC. His tenure on the appellate bench spanned seven years during a period of significant legal development in Britain.
