Perverting the course of justice is an offence committed when a person prevents justice from being served on him/herself or on another party. In England and Wales it is a common law offence, carrying a maximum sentence of life imprisonment. Statutory versions of the offence exist in Australia, Canada, Hong Kong, Ireland, and New Zealand. The Scottish equivalent is defeating the ends of justice, while the South African counterpart is defeating or obstructing the course of justice.

This offence, and the subject matter of the related forms of criminal conspiracy, have been referred to as:
- Perverting the course of justice
- Interfering with the administration of justice
- Obstructing the administration of justice
- Obstructing the course of justice
- Defeating the due course of justice
- Defeating the ends of justice

This proliferation of alternative names has been described as "somewhat confusing".
This offence is also sometimes referred to as "attempting to pervert the course of justice". This is potentially misleading.

It is not a form of the offence of attempt, and it would be erroneous to charge it as being contrary to section 1(1) of the Criminal Attempts Act 1981.
