Distance from Florida to Cuba

The shortest distance between the United States and Cuba is between Key West, Florida and Havana, Cuba:

• 90 nautical miles (103 statute miles / 166 km).
• By air: ~45 minutes (charter/private; commercial flights routed longer).
• By fast ferry (historical): ~3–4 hours (currently no scheduled service).

Other Florida–Cuba distances:

• Miami → Havana: ~230 mi (370 km)
• Fort Myers → Havana: ~330 mi (530 km)
• Pensacola → Havana: ~560 mi (900 km)

The Florida Straits separate the two; the Gulf Stream flows northward at 3–5 knots, a factor for mariners and migrants alike.
