Marxism Today, disestablished in 1991, was the theoretical magazine of the Communist Party of Great Britain. It was particularly important during the 1980s under the editorship of Martin Jacques. Through Marxism Today, Jacques, amongst others, coined the term Thatcherism and believed they were deconstructing the ideology of the government of the then Prime Minister of the United Kingdom, Margaret Thatcher, through their theory of New Times. It was also a venue for the influential British Cultural Studies of Stuart Hall.
A "special issue" was published in 1998, seven years after the magazine's demise. Until 1998, the New Statesman magazine described itself on an inside page as "incorporating" Marxism Today (among other titles).
