Estádio do Mar is a light rail station on the Porto Metro system in the municipality of Matosinhos, Portugal.

The station is on line A of the Metro, which provides a direct connection to the centre of the city of Porto.

After the completion of the port works in 1893, this line was adapted for the transport of passengers and goods, with connections to the to the existing Porto to Póvoa and Famalicão narrow gauge line, allowing direct services to be operated between Porto-Boavista station [pt] and the port.

To the east of the station, where the metro curves to the left, the old line continued straight on.

The new station was on the first section of the Porto Metro to open and was inaugurated on 7 December 2002, with commercial services starting on 1 January 2003.
