Spector v. Norwegian Cruise Line Ltd., 545 U.S. 119 (2005), was a United States Supreme Court decision that determined (in a 6–3 decision) that the Americans with Disabilities Act (ADA) applies to foreign cruise ships in American waters.

Douglas Spector and the four other disabled plaintiffs use mobility scooters and wheelchairs.

Spector had purchased premium tickets, which were marketed as more handicap friendly.

He had limited or no access to swimming pools, restaurants, elevators, and public restrooms because of physical barriers.

The cruise line's ships, however, were based out of Miami ports.
