Which countries are the major producers of olive oil?

As of 2017, over 96.8% of olive oil production is centered across Mediterranean countries, with around 62% of total production specifically being within the EU. The top five producers of olive oil in order are Spain, Italy, Greece, Turkey, and Morocco. The USDA predicted that the overall production of olive oil would enter its third consecutive year of decline in the 2020-21 period, lowering from 3.12M MT in 2019-20 to 3.03M MT. However, most of this decline is primarily associated with the producer's Turkey and Tunisia, who together comprise 14.4% of global production and are both predicted to have off years for olive oil. Tunisia specifically is expected to have a 35% decrease compared to the previous season. EU countries will likely reflect similar production yields as the already disappointing 2018-19 season according to the USDA.
