The main objective of this research is to study Egyptian Oranges' competitiveness in major foreign markets. To achieve its objective, some competitive indicators have been applied for the studies crop on the level of the competitive countries. In addition to, the research represented in an estimation almost ideal demand system (AIDS), that depends on measuring the impact of change in competitive countries export prices in certain markets and change in total expenditures on commodity imports in imported market on Egypt market share. Some of the results of the research are: 1- The Egyptian production of the oranges taking the seventh rank in production in the world, but Egypt occupies the third rank among the world's exporters of oranges by exports represent about 12% of the total world exports of oranges during the period (2008-2012). 2- The annual rate of increase in the quantity of production, the quantity of exports and the value of exports for the Egyptian oranges exports were estimated at 3.8%, 16.4% and 22.3% respectively, for the period (1999-2012). 3- By studying the geographical distribution of the quantity of Egypt's exports of oranges, the Saudi Arabia is the largest market where imports about 23%, Russia ranked second rank, where imports about 21% of the total Egyptian exports of oranges. 4- Applying (AIDS) in Saudi market showed that price elasticity of demand for Egyptian oranges reached -0.728.  It means that the demand of Saudi market on Egyptian oranges in non elasticity. The results of cross-elasticity indicated that the oranges of both South Africa and Lebanon have not a competitiveness relationship with Egyptian oranges in Saudi market. The estimates of elasticity of expenditure reached 1.11%. 5- Applying (AIDS) in Russian market showed that price elasticity of demand for Egyptian oranges reached -0.32.  The results of cross-elasticity indicated that substitution relationship between oranges exported from Egypt and that from Morocco in case the price of one of them increases, a complementary relationship between Egyptian oranges exports South Africa oranges exports.  The estimates of elasticity of expenditure reached 1.52%. 6- Applying (AIDS) in UK's market showed that price elasticity of demand for Egyptian oranges reached -6.31.  It means that the demand of UK's market on Egyptian oranges is elasticity. The positive signs of cross-elasticity pointed out that the oranges prices of South Africa, Morocco and Spain have a competitiveness relationship with Egyptian oranges in the UK's market. The estimates of elasticity of expenditure reached 3.68%. Finally, the research recommends that, it is necessary to work to keep our share in the major markets, Saudi, Russian, Ukraunian markets by integrated a strategic planning for oranges production for export. It is necessary to preservate the general level of prices of exports of the UK's market. It is necessary to provide an information base to serve the production sector and the export sector.
