The Slovenian Competition Protection Agency (CPA) is an authority with the powers of enforcing competition rules. It was established in 2013 after reorganisation of the former Slovenian Competition Protection Office and is now organised as an independent administrative authority, responsible for the enforcement of antitrust and merger control rules in Slovenia.

The CPA assesses alleged restrictive agreements and abuses of a dominant position. In cases when anti-competitive practice also affects trade between EU member states, the CPA will apply articles 101 and 102 of the Treaty on the Functioning of the European Union (TFEU).

Following receipt of a notification, CPA examines whether a concentration is compatible with the rules on competition, and after the procedure is concluded, it approves, prohibits or conditionally approves the concentration.
