PRINCE2 (PRojects IN Controlled Environments) is a structured project management method and practitioner certification programme. PRINCE2 emphasises dividing projects into manageable and controllable stages.

It is adopted in many countries worldwide, including the UK, western European countries, and Australia. PRINCE2 training is available in many languages.

PRINCE2 was initially developed as a UK government standard for information systems projects. In July 2013, ownership of the rights to PRINCE2 was transferred from HM Cabinet Office to AXELOS Ltd, a joint venture by the Cabinet Office and Capita, with 49% and 51% stakes respectively.
