Masjid (Marathi: मशिद), also known as Masjid Bunder, is a railway station in South Mumbai on the Central and Harbour lines of the Mumbai Suburban Railway. It is the penultimate stop for all trains on those lines in the "up" direction. It was opened in 1877. Contrary to popular belief, the station is not named after a masjid (mosque) but a synagogue, the 200-year-old Gate of Mercy Synagogue near a once thriving Jewish neighbourhood, popularly known as Juni Masjid by locals.
The station has 4 platforms (2 for Harbour Line & 2 for Main Line). The volume of passengers on this station is very high due to different wholesale markets (i.e., Crawford Market) surrounding the station. These markets, referred to as bazaars give access to the shops of wholesale merchants, called stockists.
Stockists from iron market (lokhand bazaar) which situated on the Eastern side of Masjid railway station and diamond traders situated on western side are known to make trades of millions of rupees each day in the markets. The south end towards CST gives access to Yousuf Mehar Ali Road, Jama Masjid, Kalbadevi, Crawford Market, Mandvi and the surrounding area.
Due to the docks, Masjid is a prominent area recognized as the hub of the larger shipping and maritime companies of India. The first office of the Reliance Commercial Corporation was set up at the Narsinathan Street in Masjid Bunder
