Nigeria has been ranked as the 36th most corrupt country globally in the 2025 Corruption Perceptions Index (CPI)released by Transparency International, a global anti-corruption watchdog.
In the latest CPI report, Nigeria scored 26 points out of 100, where 0 indicates a highly corrupt public sector and 100reflects very clean institutions. The country placed 142nd out of 182 countries, slipping two spots from its 140thposition in 2024.
Despite sliding in the overall ranking, Nigeria retained its status as the 36th most corrupt nation worldwide, sharing the position with countries such as Cameroon, Guatemala, Guinea, Kyrgyzstan, and Papua New Guinea.
The Corruption Perceptions Index assesses perceived levels of public-sector corruption across countries and territories on a 0–100 scale, with lower scores indicating higher perceived corruption.
Globally, Denmark topped the index as the least corrupt country with 89 points, followed by Finland, Singapore and New Zealand among the cleanest nations.
No African country made the top 10 least corrupt list, though nations like Seychelles, Cabo Verde, and Botswana were among the continent’s better performers. Meanwhile, countries such as South Sudan, Somalia, and Venezuela ranked among the most corrupt.
Transparency International noted that corruption remains a major global challenge, with many nations showing stagnation or decline in efforts to curb graft, contributing to weak governance and public distrust.
