The New Statesman is a British political and cultural newsmagazine published in London. Founded as a weekly review of politics and literature on 12 April 1913, it was at first connected with Sidney and Beatrice Webb and other leading members of the socialist Fabian Society, such as George Bernard Shaw, who was a founding director.

Today, the magazine is a print–digital hybrid. According to its present self-description, it has a liberal and progressive political position. Jason Cowley, the magazine's editor, has described the New Statesman as a publication "of the left, for the left" but also as "a political and literary magazine" with "sceptical" politics.

The magazine was founded by members of the Fabian Society as a weekly review of politics and literature. The longest-serving editor was Kingsley Martin (1930–1960), and the current editor is Jason Cowley, who assumed the post in 2008.

The magazine has recognised and published new writers and critics, as well as encouraged major careers. Its contributors have included John Maynard Keynes, Bertrand Russell, Virginia Woolf, Christopher Hitchens, and Paul Johnson. Historically, the magazine was affectionately referred to as "The Staggers" because of its crises of funding, ownership, and circulation. The nickname is now used as the title of its politics blog.

Circulation was at its highest in the mid-1960s at 93,000. The magazine encountered substantial difficulties in the following decades as readership fell, but it was growing again by the mid-2010s. In 2020, the certified average circulation was 36,591. Traffic to the magazine's website that year reached a new high with 27 million page views and four million distinct users. Associated websites are CityMetric, Spotlight and NewStatesman Tech. In 2018, New Statesman America was launched.
