Hawaii's Neighbors: None. It's the Most Isolated U.S. State.

Hawaii has no neighboring states. It is an archipelago in the central Pacific Ocean, approximately:

• 3,850 km (2,390 mi) from California (nearest continental U.S. coast).
• 6,200 km (3,850 mi) from Japan.
• 8,200 km (5,100 mi) from the Philippines.

The state comprises 137 volcanic islands spanning 2,400 km (1,500 mi), but only eight main islands are inhabited. The entire state is surrounded by the Pacific—no land borders, no shared water boundaries with other U.S. states.

Closest Political Entities

• U.S. territories: Johnston Atoll (uninhabited, ~1,400 km SW), Palmyra Atoll (~1,600 km S).
• Foreign nations: Kiribati (Line Islands) ~2,000 km S; Marshall Islands ~3,500 km SW.

This extreme isolation shapes Hawaii's unique ecology (high endemism), logistics (90%+ goods imported), energy (historically oil-dependent), and culture (distinct Polynesian-rooted identity within the U.S.).
