The Daily Express is a national daily United Kingdom middle-market newspaper printed in tabloid format. Published in London, it is the flagship of Express Newspapers, owned by publisher Reach plc. It was first published as a broadsheet in 1900 by Sir Arthur Pearson. Its sister paper, the Sunday Express, was launched in 1918. In June 2022, it had an average daily circulation of 201,608.

The paper rose to become the largest circulation newspaper in the world under Lord Beaverbrook, going from 2 million in the 1930s to 4 million in the 1940s. It was acquired by Richard Desmond's company Northern & Shell in 2000. Hugh Whittow was the editor from February 2011 until he retired in March 2018. In February 2018 Trinity Mirror acquired the Daily Express, and other publishing assets of Northern & Shell, in a deal worth £126.7 million. To coincide with the purchase the Trinity Mirror group changed the name of the company to Reach. Hugh Whittow resigned as editor and Gary Jones took over as editor-in-chief soon after the purchase.

The paper's editorial stances have often been seen as aligned to Euroscepticism and supportive of the UK Independence Party (UKIP), and other right-wing factions including the European Research Group (ERG) of the Conservative Party.
