Sion (/ˈsaːjən/; IAST: Śīv [ʃiːʋ]) is a neighbourhood of Mumbai, Maharashtra, India. In the 17th century the village formed the boundary between Mumbai and Salsette Island. It marks the boundary between the city and its suburbs and holds historical significance due to its strategic location. The name remained even after Mumbai was joined to the Salsette and extended up to Mulund. Sion is known for its blend of residential, commercial, and industrial developments and offers excellent connectivity to various parts of Mumbai. One of the local historical places in Sion is a hilltop garden commonly known as Sion Fort or Sheevon Killa in the Marathi language.
