The Data Protection Commission (DPC) is the national independent authority responsible for upholding the fundamental right of individuals in the EU to have their personal data protected. The DPC is the Irish supervisory authority for the General Data Protection Regulation (GDPR), and also has functions and powers related to other important regulatory frameworks including the Irish ePrivacy Regulations (2011) and the EU Directive known as the Law Enforcement Directive.

The Data Protection Act 2018, which became law on 25 May 2018 established a new Data Protection Commission (DPC). The new Commission is the national independent supervisory authority in Ireland with responsibility for upholding the fundamental right of the individual to have their personal data protected.  The DPC’s statutory powers, functions and duties derive from the Data Protection Act 2018, General Data Protection Regulation, Law Enforcement Directive, as well as from the Data Protection Acts 1988 to 2003 which, inter alia, gives effect to Council of Europe Convention 108.
