Where Is Mauritius? Geography, Geology, and Strategic Location in the Indian Ocean

Mauritius is a sovereign island nation in the Indian Ocean, approximately 2,000 km (1,200 miles) off the southeast coast of Africa. It lies at the crossroads of Africa, Asia, and the Global South—a geographic reality that has shaped its history, demography, and economy.

Precise Coordinates & Context

• Latitude/Longitude: 20°10′S, 57°30′E (Port Louis).
• Neighbors:
  • Réunion (France): 220 km southwest (visible on clear days).
  • Rodrigues (Mauritius dependency): 560 km east-northeast.
  • Tromelin Island (France): 430 km north-northwest.
  • Madagascar: ~800 km west.
  • Mahé, Seychelles: ~1,700 km northeast.
• Group: Mascarene Islands (with Réunion, Rodrigues). Volcanic origin, 8–10 Ma.
• Continental Shelf: Sits on the Mauritius Plateau, part of the submerged Mascarene Plateau—a microcontinent fragment (Mauritia) from Gondwana breakup.

Political Geography

• Continent: Africa (African Union member).
• Subregion: Eastern Africa (UN geoscheme).
• Exclusive Economic Zone (EEZ): 2.3 million km² — vast maritime domain for fisheries, potential seabed minerals.
• Dependencies: Rodrigues (autonomous), Agaléga, St. Brandon (Cargados Carajos), Chagos Archipelago (disputed — UK/US base on Diego Garcia; ICJ 2019 advisory opinion: UK must decolonize).

Physical Geography

• Area: 2,040 km² (main island 1,865 km²).
• Topography: Central plateau (300–600 m) ringed by basaltic mountain ranges (Moka, Grand Port, Black River). Highest: Piton de la Petite Rivière Noire (828 m).
• Coastline: 177 km; encircling coral reef (lagoon) — calm turquoise water, white sand beaches.
• Climate: Tropical maritime; SE trade winds. Summer (Nov–Apr): warm, humid, cyclone risk. Winter (May–Oct): cooler, drier.
• Biodiversity: High endemism (dodo extinct; echo parakeet, pink pigeon, kestrel recovered). Coral reefs, mangroves, ebony forests.

Strategic Significance

• Historic: Uninhabited until Dutch (1598), French (1715), British (1810). Sugar plantation economy → indentured labor from India (1834–1910) → Indo-Mauritian majority (68%).
• Modern: "Star and Key of the Indian Ocean." Financial services, tourism, textile, ICT, seafood hub. Gateway for India-China-Africa trade. Hosts Indian Ocean Rim Association (IORA).
• Geopolitics: India's "SAGAR" (Security and Growth for All in the Region); China's Belt & Road; France (Réunion) & UK (BIOT) military presence. Mauritius champions African-Indian Ocean identity.

Quick Reference

Mauritius is more than a dot on the map—it is a microcontinent of culture, a biodiversity hotspot, and a strategic pivot in the Indian Ocean's evolving geopolitics.
