The Konkan Railway (Railway Symbol:KR) is a railway line which runs along the Konkan coast of India. It was constructed and is operated by the Konkan Railway Corporation. It runs from Mangalore in Karnataka to Roha in Maharashtra through Goa, along the west coast of India and Western Ghats.

Until the Konkan Railway started its operations, the two important port cities Mangalore and Mumbai were not directly connected by the railway network. In mid of twentieth century people travelling to Mumbai from Mangalore and adjoining areas would go to Kadur or Birur by bus and then catch a train to Mumbai ( Bombay then ). In 1970's National Highway 17 (NH-17) was built to connect these cities by road. Direct bus services started between these two cities after the construction of NH-17. Even though economic reasons provided a strong need to connect these two cities, the region through which the railway track passed was geographically very tough and would be an engineering challenge. Due to the uneven terrain of the region, railway lines were not laid for many years.
