Strait of Lombok
A deep-water Indonesian passage linking regional seas to the Indian Ocean
The Strait of Lombok is a narrow deep-water passage between Bali and Lombok in Indonesia, linking waters north of the archipelago with the Indian Ocean and serving as an alternative route for large ships.
Definition
The Strait of Lombok is a maritime passage in Indonesia located between the islands of Bali and Lombok. It forms part of the Indonesian archipelago's network of sea lanes and connects waters north of the islands with the Indian Ocean.
Unlike some shallower regional passages, the Strait of Lombok is known for its deep-water profile, making it relevant for larger commercial and naval vessels that may not be able to use narrower or shallower routes as efficiently.
Why It Matters
The Strait of Lombok matters because it provides an alternative maritime route through Southeast Asia when the Malacca Strait is congested, constrained, or strategically sensitive. This gives it persistent importance for shipping resilience and naval mobility.
Its position within Indonesia also places it inside a wider geopolitical conversation about archipelagic sea lanes, freedom of navigation, maritime security, and the movement of trade between the Pacific and Indian Ocean systems.
GPS should watch the Strait of Lombok as part of the broader Indo-Pacific chokepoint system. Its relevance increases when shipping, naval planning, or regional security analysis focuses on alternatives to the Malacca Strait, Indonesian archipelagic sea lanes, and access between the Pacific and Indian Oceans.
