Afcons Infrastructure Limited is an Indian multinational construction and engineering company based in Mumbai.

The company is involved in infrastructure EPC projects such as bridges, flyovers, metros, railway lines, tunnels, highways, ports and marine works, barrages, and oil and gas structures.

In the initial years, the company undertook foundation work of office buildings in Mumbai's then-business district Nariman Point.

In 1976, the Swiss partner exited the joint venture by selling its stake to an employees-led consortium, owing to the Foreign Exchange Regulation Act legislation passed in 1973 which affected its business viability.

[4][5] The company later expanded its business interests beyond foundation engineering to include marine construction (jetties, docks and harbours) and transportation works (roads and bridges).
