East Sikkim (पूर्व सिक्किम) is a former district in eastern Sikkim, India, whose territory is now administered as Gangtok and Pakyong districts. Centred on Gangtok, the state capital, the area is known for Himalayan scenery, Buddhist monasteries and routes towards Tsomgo Lake and Nathu La on the India–China border.
Nepali, Bhutia, Lepcha and other communities contribute to its multilingual culture. Buddhist and Hindu festivals, local markets and varied food traditions shape everyday life. Tourism, government services, commerce and agriculture support livelihoods. Important landmarks across the former district include Rumtek Monastery, Gangtok’s pedestrianised MG Marg and Pakyong Airport. Mountain villages coexist with expanding urban neighbourhoods.
Common civic concerns include reliable water supplies, waste management, traffic congestion and access to healthcare and education. Landslides, heavy rainfall and road disruptions make resilient infrastructure and disaster preparedness important. Residents also have a stake in protecting forests and water sources while balancing tourism, construction and employment opportunities.
