Luxembourg Leaks (sometimes shortened to Lux Leaks or LuxLeaks) is the name of a financial scandal revealed in November 2014 by a journalistic investigation conducted by the International Consortium of Investigative Journalists. It is based on confidential information about Luxembourg's tax rulings set up by PricewaterhouseCoopers from 2002 to 2010 to the benefits of its clients. This investigation resulted in making available to the public tax rulings for over three hundred multinational companies based in Luxembourg.

The LuxLeaks' disclosures attracted international attention and comment about tax avoidance schemes in Luxembourg and elsewhere.[1] This scandal contributed to the implementation of measures aiming at reducing tax dumping and regulating tax avoidance schemes beneficial to multinational companies.

The judicial aspects of this case concern the persons charged by Luxembourg justice for participating in the revelations. No multinational company was charged. The LuxLeaks trial took place in spring 2016 and led to the condemnation of the two whistleblowers. The appeal trial's judgment delivered in March 2017 confirmed their condemnation. Following a new appeal, the Luxembourg higher Court rendered in January 2018 a distinct judgment for the two defendants and fully granted the whistleblower status for one of them.
