A December 2018 report of a poll by the Publishers Audience Measurement Company stated that the paper's print edition was found to be the most trusted in the UK in the period from October 2017 to September 2018.

In an Ipsos MORI research poll in September 2018 designed to interrogate the public's trust of specific titles online, The Guardian scored highest for digital-content news, with 84% of readers agreeing that they "trust what see in it". Frequent typographical errors during the age of manual typesetting led Private Eye magazine to dub the paper the "Grauniad" in the 1970s, a nickname still occasionally used by the editors for self-mockery. The paper's readership is generally on the mainstream left of British political opinion, and the term " Guardian reader" is used to imply a stereotype of liberal, left-wing or " politically correct" views. The newspaper has an online edition,, as well as two international websites, Guardian Australia (founded in 2013) and Guardian US (founded in 2011). As of July 2021, its print edition had a daily circulation of 105,134. Since 2018, the paper's main newsprint sections have been published in tabloid format. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. It is considered a newspaper of record in the UK. Profits are reinvested in its journalism rather than distributed to owners or shareholders.

The trust was converted into a limited company in 2008, with a constitution written so as to maintain for The Guardian the same protections as were built into the structure of the Scott Trust by its creators. The trust was created in 1936 to "secure the financial and editorial independence of The Guardian in perpetuity and to safeguard the journalistic freedom and liberal values of The Guardian free from commercial or political interference". Along with its sister papers, The Observer and The Guardian Weekly, The Guardian is part of the Guardian Media Group, owned by the Scott Trust. It was founded in 1821 as The Manchester Guardian, and changed its name in 1959.

The Guardian is a British daily newspaper.
