This is a comparative study that examined the relationship between the Big Five personality factors and English language speaking anxiety among Moroccans (N=270) and Koreans (N=257), who completed the International Personality Item Pool Big Five Inventory and the English Language Speaking Anxiety Scale. The results indicate that Openness and Neuroticism were the only significant predictors of English language speaking anxiety in the two countries, noting that Openness was the strongest significant predictor in Morocco, whereas Neuroticism was the strongest significant predictor in Korea. Implications indicated that assessing the personality of students may predict those who will experience these anxieties.
