Charles Marowitz (26 January 1932 – 2 May 2014) was an American critic, theatre director, and playwright, regular columnist on Swans Commentary. He was perhaps best known for being a "close collaborator" with Peter Brook at the Royal Shakespeare Company and for founding and directing The Open Space Theatre, both in London.
He is also the co-founder of Encore magazine which was published between 1954 and 1965, and co-editor of The Encore Reader: A Chronicle of the New Drama (1965). He was a regular contributor to publications such as The New York Times, The Times (London), TheaterWeek, and American Theatre and was the lead critic on the Los Angeles Herald-Examiner until it ceased publication.
He was additionally the author of Murdering Marlowe, which imagines a rivalry between William Shakespeare and Christopher Marlowe, which was selected as a finalist for the GLAAD Media Awards of 2002, and of the 1987 Broadway play Sherlock's Last Case with Frank Langella in the lead role.
His free adaptations of Shakespeare have been collected in The Marowitz Shakespeare. He died of complications from Parkinson's disease in 2014 at the age of 80.
