A peer reviewed article is an academic paper that has been reviewed by several experts in the same discipline before it is accepted for publication. Usually, the peer reviewers give the author(s) feedback and suggestions for change, the author(s) resubmits the paper, and the peers review it again. This process gives the paper more credibility in the academic world.
When you search for an academic article, many databases have an option to filter the results to only peer-reviewed.
