Mumbai Suburban district (Marathi: Mumbai Upanagar Jilha) is one of the 36 districts of the state of Maharashtra in western India. It forms a major portion of the metropolitan area of Mumbai, lying to the north of Mumbai City district and constituting the suburban belt of the city. The district is part of the Konkan division and is administered separately from the adjoining Mumbai City district, though both together make up the city of Greater Mumbai.

Mumbai Suburban district occupies the central and northern portions of Salsette Island. It is bounded by the Arabian Sea on the west, Thane Creek on the east, Mumbai City district to the south, and Thane district to the north. The terrain includes coastal plains, creeks, and forested hills, with the Sanjay Gandhi National Park forming a large protected area in the northern part of the district. Important water bodies and creeks include the Mahim Creek, Mithi River, and Malad Creek.
The district is divided into three talukas: Andheri, Borivali, and Kurla. The administrative headquarters is located at Bandra. While the District Collector handles revenue administration, civic services across the district are provided by the Brihanmumbai Municipal Corporation, which also serves Mumbai City district. The district falls under the jurisdiction of the Bombay High Court.
Historically, the area now forming Mumbai Suburban district was part of Salsette Island, ruled in succession by the Silharas, Yadavas, the Delhi and Gujarat Sultanates, the Portuguese, and from 1782 by the British East India Company after the Treaty of Salbai. The suburbs grew rapidly with the expansion of the railway network in the late 19th and 20th centuries, particularly along the Western and Central lines. The Mumbai Suburban district was carved out of Greater Bombay district on 1 October 1990, when Greater Bombay was bifurcated into Mumbai City and Mumbai Suburban districts for administrative convenience.
Mumbai Suburban is among the most populous districts in India and is highly urbanised. It is linguistically and religiously diverse, with Marathi as the official language and Hindi, English, Gujarati, Urdu, and several other languages widely spoken. The district contains a large share of Greater Mumbai's residential population, with neighbourhoods ranging from planned suburbs to extensive informal settlements, including parts of Dharavi.
The district is a major economic hub of India, hosting key commercial and industrial nodes. Significant centres include the Bandra Kurla Complex (BKC), a planned business district that houses the National Stock Exchange of India, several banks, and corporate headquarters; the Santacruz Electronics Export Processing Zone (SEEPZ) in Andheri; and the Hindi film and television industry, popularly known as Bollywood, centred around Film City in Goregaon and studios in Andheri. The Chhatrapati Shivaji Maharaj International Airport at Sahar and the domestic terminal at Santacruz are located within the district.
The district hosts several prominent institutions, including the Indian Institute of Technology Bombay at Powai, the SNDT Women's University campus, the Tata Institute of Social Sciences (Deonar), and numerous colleges affiliated to the University of Mumbai. Major hospitals include Lilavati Hospital (Bandra), Kokilaben Dhirubhai Ambani Hospital (Andheri), and the Rajawadi and Bhabha hospitals run by the BMC.
Mumbai Suburban district is central to the economic, cultural, and political life of Maharashtra and India. It contributes substantially to the state's revenue, hosts the financial and entertainment industries that define modern Mumbai, and serves as the residential base for the bulk of Greater Mumbai's workforce. Its rapid urbanisation has also made it a focal point for issues of housing, transport infrastructure, and environmental management in Indian metropolitan governance.
