The Bombay Engineer Group, or the Bombay Sappers as they are informally known, are a regiment of the Corps of Engineers of the Indian Army. The Bombay Sappers draw their origin from the erstwhile Bombay Presidency army of the British Raj. The group has its centre in Khadki, Pune in Maharashtra state. The Bombay Sappers have gone on to win many honours and awards, both in battle and in peacetime, throughout the 19th and 20th centuries, both before and after Independence. The gallantry awards won include the British Victoria Cross and the French Legion of Honour before independence, as well as the Param Vir Chakra and Ashok Chakra as part of Independent India. The Group has also made its mark in peacetime activities such as sport, adventure, disaster relief, aid to civil authority and prestigious construction projects.

The Bombay Presidency or Bombay Province, also called Bombay and Sind (1843–1936), was an administrative subdivision (province) of British India and later the Dominion of India, with its capital in the city that came up over the seven islands of Bombay. The first mainland territory was acquired in the Konkan region with the Treaty of Bassein. Poona was the summer capital.
