The Big Issue is a street newspaper founded by John Bird and Gordon Roddick in September 1991 and published in four continents. The Big Issue is one of the UK's leading social businesses and exists to offer homeless people, or individuals at risk of homelessness, the opportunity to earn a legitimate income, thereby helping them to reintegrate into mainstream society. It is the world's most widely circulated street newspaper.

Street newspapers are newspapers or magazines sold by homeless or poor individuals and produced mainly to support these populations. Most such newspapers primarily provide coverage about homelessness and poverty-related issues, and seek to strengthen social networks within homeless communities. Street papers aim to give these individuals both employment opportunities and a voice in their community. In addition to being sold by homeless individuals, many of these papers are partially produced and written by them.
