The World Justice Project's Rule of Law Index for 2019 ranked Lebanon in 89th place among 126 countries around the world and in sixth place among eight countries in the Middle East & North Africa (MENA) region. Lebanon also came in 32nd place among 38 upper middle-income countries (UMICs) included in the survey. Based on the same set of countries, Lebanon's global rank improved by three spots from the 2017-18 survey, while its rank among MENA countries improved by one spot year-on-year.

The index measures the implementation of the rule of law by aggregating 44 sub-factors into eight factors that are Constraints on Government Powers, Absence of Corruption, Open Government, Fundamental Rights, Order & Security, Regulatory Enforcement, Civil Justice and Criminal Justice. The scores and rankings of each factor and sub-factor are based on the results of an opinion poll of the general public and of a survey of legal professionals in each country. The scores range from zero to one point, with a score of one point reflecting the strongest adherence to the rule of law. The general population poll covers only the three major urban areas in each country. The Lebanon survey covered 1,000 participants in Beirut, Sidon and Tripoli.

Globally, the implementation of the rule of law in Lebanon is better than in the Philippines, Tanzania and Zambia, and is weaker than in El Salvador, Ecuador and Russia among economies with a GDP of $10bn or more. Also, the rule of law in Lebanon is more effective than only in Iran and Egypt in the MENA region. Lebanon received a score of 0.47 points in the 2019 survey, unchanged from the 2017-18 survey. Lebanon's score was lower than the global average score of 0.56 points, the UMICs' score of 0.53 points and the MENA region's average score of 0.5 points.
