Navi Mumbai International Airport (NMIA) is an under-construction greenfield international airport being built at Ulwe Kopar-Panvel in Maharashtra, India. It will be the second international airport for the Mumbai Metropolitan Region, functioning alongside Chhatrapati Shivaji Maharaj International Airport (CSIA) as India's first urban multi-airport system. The first phase of the airport will be able to handle 10 million passengers per annum (MPPA). The airport will then be expanded to full capacity and equipped to support more than 60 MPPA.

Navi Mumbai International Airport Limited (NMIAL) is executing the project. It is a Special Purpose Entity formed by the GVK group and City and Industrial Development Corporation (CIDCO). They will hold 74% and 26% equity shares of NMIAL respectively. CIDCO is the nodal government agency for the project, which will be built through public–private partnership (P3) on a 'design, build, finance, operate and transfer' (DBFOT) basis.
