Least Corrupt Countries 2025

Corruption is a term used to describe dishonest or fraudulent behavior by someone in power. When applied on a national scale, “corruption” refers to government leaders who abuse their power, take bribes, or commit fraud or other disreputable acts to increase their own wealth and/or power instead of helping the people they are meant to serve. Corruption is an unfortunate reality in many nations around the world, especially low-income countries, developing countries, and least developed countries, which have fewer checks and balances on their rulers’ powers. While no single data indicator directly measures corruption in a nation, many indicators offer indirect-but-accurate evidence of the presence or absence of corruption.

Corruption Perceptions Index

One of the most comprehensive and trusted measures of corruption around the world is the Corruption Perceptions Index (CPI), which is published annually by Transparency International. The 2022 CPI gave 180 countries a score of 0 (highly corrupt) to 100 (very clean) based upon their perceived levels of public sector corruption. As in previous years, more than two-thirds of the world’s countries scored below 50 in the 2022 rankings, resulting in an average score of 43 for the tenth year in a row, while 26 countries have fallen to their lowest scores yet. The top ten least corrupt appear below, followed by the full list further down the page.

Top 10 Least Corrupt Countries in the World (CPI 2022)

The list of least corrupt countries often includes many of the same countries as would a list of the most developed or high income countries. On the other end of the spectrum are the most corrupt countries in the world, such as South Sudan, Syria, Somalia, and Venezuela. As previously mentioned, these tend to also be low-income countries, developing countries, or least developed countries.
