The Paradise Papers is a set of 13.4 million confidential electronic documents relating to offshore investments that were leaked to the German newspaper Süddeutsche Zeitung. The newspaper shared them with the International Consortium of Investigative Journalists, and a network of more than 380 journalists, and some of the details were made public on 5 November 2017.

The documents originate from the offshore law firm Appleby, the corporate services providers Estera and Asiaciti Trust, and business registries in 19 tax jurisdictions. They contain the names of more than 120,000 people and companies. Among those whose financial affairs are mentioned are, separately, Prince Charles and Queen Elizabeth II, President of Colombia Juan Manuel Santos, and U.S. Secretary of Commerce Wilbur Ross. At 1.4 terabytes in size, this is second only to the Panama Papers in 2016 as the biggest data leak in history.
