Objective: Tolerance is considered one of the most important values in any society. The present study aimed to validate the Tolerance Index on the Saudi society. Method: A 2019 Tolerance Index (56 items) by the King Abdulaziz Center for National Dialogue was used. A total of 1071 participants completed the survey. The sample was randomly selected using geographical sampling. The Exploratory Factor Analysis (EFA) was used to validate the Tolerance Index. Result: The principal components analysis, along with the orthogonal rotation matrix (Varimax rotation) revealed that 35 items of the Tolerance Index were loaded on six main factors: twelve items were loaded onto two social and cultural factors; eight items were loaded onto two economic factors; four items were loaded onto one political factor; and 11 items were loaded onto one religious factor. Conclusion: The Tolerance Index is valid and is a reliable index that can be used in the Saudi society.
