The shortest distance between Florida and Cuba, measured from Key West to the northern coast of Cuba, is approximately 90 miles (145 kilometers). This proximity has defined the geographical relationship between the two landmasses for centuries. The measurement represents a straight-line distance, and actual travel routes may vary depending on the mode of transportation and specific points of origin and destination.
This close geographical relation has fostered significant historical, political, and cultural ties between the United States and Cuba. Throughout history, this nearness has facilitated migration, trade, and at times, conflict. The relatively short expanse of water has also played a crucial role in shaping the demographics and cultural landscape of South Florida, particularly in the Miami area.
