Seas Bordering Russia

Russia's vast coastline touches 13 seas across three oceans:

Arctic Ocean Seas

• Barents Sea
• Kara Sea
• Laptev Sea
• East Siberian Sea
• Chukchi Sea
• White Sea (inland)

Pacific Ocean Seas

• Bering Sea
• Sea of Okhotsk
• Sea of Japan (East Sea)

Atlantic Ocean Seas (via marginal seas)

• Baltic Sea (Gulf of Finland)
• Black Sea
• Sea of Azov
• Caspian Sea (landlocked, saline lake—often listed)

This gives Russia the world's longest coastline (~37,650 km) and strategic access to multiple ocean basins.
