Trombay is a northeastern suburb in Mumbai, India, with Mankhurd as the closest railway station on the Harbour Line of the Mumbai Suburban Railway.

Trombay was called Neat's Tongue because of its shape. Once, it was an island nearly 5 km East of Mumbai and was about 8 km in length and 8 km in width. The island contains several ruins of Portuguese churches from the 1620s and 1630s.

In 1928, the Great Indian Peninsular Railway opened the Trombay-Andheri line called the Salsette Trombay Railway or Central Salsette Tramway.

The original inhabitants of Trombay were fisherman - due to its proximity to the Thane creek and the Arabian Sea. It was called as "Turbhe" (not to be confused with another area called Turbhe in Navi Mumbai) in the local language. Pailipada, near Trombay Village, is also very old, having one of the oldest masjid in Mumbai.Trombay gaothan is old village of Turbhekar`s family. Pailipada has majority Muslim population. In 1976 the Janata Colony area was relocated by BARC by order of the central government and formed as Cheetah Camp.
