Raigad District (Marathi: रायगड जिल्हा), is a district in the state of Maharashtra, India.  It is located in the Konkan region. The district was renamed after Raigad, the fort that was the former capital of the Maratha leader Shivaji Maharaj, and is located in the interior regions of the district, in dense forests on a west-facing spur of the Western Ghats of Sahyadri range. In 2011 the district had a population of 2,635,394, compared to 2,207,929 in 2001. In 2011 urban dwellers had increased to 36.91% from 24.22% in 2001.
The district is bounded by Mumbai Harbour to the northwest, Thane District to the north, Pune District to the east, Ratnagiri district to the south, and the Arabian Sea to the west. It includes the large natural harbor of Pen-Mandwa, which is immediately south of Mumbai harbour, and forming a single landform with it. The northern part of the district is included in the planned metropolis of Navi Mumbai, and its port, the Jawaharlal Nehru Port.
The district includes towns/cities of Mangaon, Roha, Panvel, Pen, Khopoli, Kharghar, Taloja, Khalapur, Uran, Patalganga, Rasayani, Nagothana, Poladpur, Alibag, Karjat and Mahad. The largest city both in area and population is Panvel. The district also includes the isle of Gharapuri or Elephanta, located in Uran tehasil (NOT TEHASIL BUT TALUKA) which has ancient Hindu and Buddhist caves.
Kulaba (also spelled Kolaba) district was split from Thane district in 1869. According to the 1872 census, Kulaba district had a population of just over 350,000 people, with 94% of the population being Hindus, and most of the remaining population being Muslims. In 1881 the population was about 382,000, with 95% of the population being Hindus.
At this point the northernmost parts of modern Raigad district were retained in Thane district. Panvel, just across the bay from Mumbai, was not included in Kolaba district until 1883, and Karjat, an area in the north-east corner of modern Raigad district, was not placed in Kolaba district until 1891. Kolaba district was subsequently renamed Raigad district.
