Transparency International is an international anti-corruption organization and global movement that works to reduce corruption in public institutions, businesses, and civic life. The organization promotes transparency, accountability, and the rule of law by combining research, policy guidance, advocacy, and practical tools for the people and institutions affected by corruption. Its work serves governments, companies, civil society groups, journalists, researchers, educators, and citizens who need reliable information on corruption risks, governance failures, and ways to hold power to account. Through its publications, data, and campaigns, Transparency International examines corruption worldwide and helps readers understand how entrenched corruption affects public services, economic growth, social trust, and sustainable development. The organization is widely known for its Corruption Perceptions Index, a comparative measure of corruption perceptions that ranks countries by perceived public-sector corruption, as well as for other indicators, rankings, and analytical reports. These resources give policymakers, compliance teams, investors, and nonprofit organizations a clearer view of corruption measures, institutional weaknesses, and the practical steps available to stop corruption in high-risk areas. The site is notable for connecting readers to a global network of national chapters, partners, and campaigns that address specific issues such as public procurement, political finance, judicial integrity, media freedom, business ethics, and anti-money laundering. It also provides educational materials, case studies, and guidance for organizations seeking to strengthen internal controls, improve procurement processes, or support civic participation. For anyone researching global corruption, evaluating country risk, or looking for evidence-based approaches to governance reform, Transparency International offers a well-known reference point for understanding the impact of corruption and the actions being taken to address it.
