Baku Archipelago is an archipelago in the Caspian Sea off the coast of Baku, the capital of Azerbaijan. The group of islands lies within the Absheron Peninsula maritime zone and has been central to regional oil industry development, maritime navigation, and ecology studies. The archipelago's islands have been shaped by Caspian Sea level changes, petroleum extraction, and urban expansion connected to Baku Port and Heydar Aliyev International Airport infrastructure.
The archipelago is located in the south-eastern sector of the Caspian Sea adjacent to the Absheron Peninsula near Baku Boulevard, Port of Baku, and the Oil Rocks facilities; it lies within territorial waters administered by Azerbaijan and proximate to Khazar District. Its maritime setting connects to regional maritime routes used by Azerbaijan Railways ferries, Iran-bound tankers, and vessels servicing the Baku–Tbilisi–Ceyhan pipeline logistics chain. The islands are often characterized by shallow surrounding shoals, navigational hazards referenced in charts by the International Hydrographic Organization and surveyed historically by Russian Imperial expeditions such as those led by Vasily Dokuchaev and later Soviet institutes like the Institute of Geography of the Azerbaijan Academy of Sciences.
Geologically the archipelago rests on deposits of the Caspian Depression and the Absheron Formation, with sedimentation influenced by Kura River discharge, Pleistocene transgressions, and Holocene regressions studied by the Geological Institute of Azerbaijan. Hydrocarbon-bearing strata beneath and around islands relate to regional petroliferous basins explored by SOCAR, BP (BP plc), and Soviet-era organizations including Azneft. The islands exhibit mud volcano influence comparable to features recorded at Gobustan National Park and are affected by sea level change events documented in research by the United Nations Educational, Scientific and Cultural Organization and the United Nations Environment Programme.
Major landforms include Nargin Island (locally known for its lighthouse and military uses), Pirallahi Island with connections to Pirallahi Oilfield development, and Boyuk Zira Island, alongside smaller islets historically named by Russian Imperial, Soviet, and Azerbaijani authorities. Several features were altered by construction linked to Soviet Navy facilities, Azerbaijan Caspian Shipping Company terminals, and industrial platforms similar to those at Oil Rocks (Neft Daşları). Cartographic records from the Imperial Russian Navy and surveys by the Hydrographic Service of the Soviet Navy list dozens of named shoals and keys used in navigation by the Caspian Flotilla and contemporary commercial fleets.
The archipelago provides habitat for seabirds documented by ornithologists working with BirdLife International and regional conservationists from the Institute of Zoology of the Azerbaijan National Academy of Sciences. Species include migrants connecting flyways monitored by the Convention on Migratory Species and coastal marsh assemblages comparable to those in Iran's Caspian littoral and Dagestan. Marine fauna around the islands intersects with populations studied for sturgeon conservation tied to the Convention on International Trade in Endangered Species of Wild Fauna and Flora and includes benthic communities affected by oil pollution incidents historically assessed by International Union for Conservation of Nature researchers.
Human use dates to historical trade routes through the Caspian Sea used by the Safavid dynasty, Russian Empire, and later Soviet Union naval and industrial operations. The islands were strategic during conflicts involving the Russo-Persian Wars and served as logistics points during Soviet-era industrialization initiatives alongside projects by Azerbaijan Democratic Republic engineers, Soviet Ministry of Oil Industry, and later State Oil Company of the Azerbaijan Republic (SOCAR). Cultural heritage links include archaeological surveys comparable to those at Gobustan Rock Art Cultural Landscape and historical accounts in archives of the Baku Governorate.
The archipelago's economy has been dominated by petroleum exploration and production involving companies such as SOCAR, BP (BP plc), LUKOIL, and service contractors engaged in offshore drilling and platform construction similar to developments on Oil Rocks. Marine transport connects island facilities to the Port of Baku, pipehead stations for the Baku–Supsa pipeline and links to regional export corridors including the North-South Transport Corridor. Local infrastructure investments have included proposals for tourism development near Baku Boulevard and industrial expansions analogous to mainland petrochemical sites in Sumgait.
Environmental challenges include oil pollution incidents, habitat degradation noted by UNEP assessments, and impacts on sturgeon fisheries regulated under multinational agreements such as the Convention on the Conservation of Migratory Species of Wild Animals. Restoration efforts reference best practices promoted by International Maritime Organization protocols and projects led by Azerbaijan Ministry of Ecology and Natural Resources in coordination with international partners including World Bank environmental programs. Conservation tensions mirror those in adjacent Caspian jurisdictions such as Russia and Iran where transboundary initiatives under the Caspian Sea Convention frameworks aim to manage pollution, fisheries, and biodiversity.
