The News International phone hacking scandal was a controversy involving the now-defunct News of the World and other British newspapers owned by Rupert Murdoch. Employees of the newspaper engaged in phone hacking, police bribery, and exercising improper influence in the pursuit of stories.

The News of the World was a weekly national "red top" tabloid newspaper published every Sunday in the United Kingdom from 1843 to 2011. It was at one time the world's highest-selling English-language newspaper, and at closure still had one of the highest English-language circulations. It was originally established as a broadsheet by John Browne Bell, who identified crime, sensation and vice as the themes that would sell most copies. The Bells sold to Henry Lascelles Carr in 1891; in 1969, it was bought from the Carrs by Rupert Murdoch's media firm News Limited. Reorganised into News International, a subsidiary of News Corporation, the newspaper was transformed into a tabloid in 1984 and became the Sunday sister paper of The Sun.
