The OSN Cup was a club football friendly tournament hosted in the Middle East, primarily in Saudi Arabia and the United Arab Emirates, during the 1990s and early 2000s. It served as a mid-season or post-season event, attracting top clubs from Europe and South America to compete against each other and regional sides. The format was typically a short knockout competition or a small group stage culminating in a final. The tournament's main characteristic was its role in bringing world-class football to the Gulf region, helping to grow the sport's popularity there. It provided fascinating cross-continental clashes outside of official UEFA or CONMEBOL competitions. While not bearing the weight of a major title, winning the OSN Cup was a mark of prestige for the participating clubs during its era.
