Tremblay is an O-Train station on the Confederation Line in Ottawa, Ontario. It is walking distance from the Ottawa train station, connecting to Via Rail Corridor inter-city rail services. The station opened on September 14, 2019 to replace the former Transitway bus rapid transit station known as Train Station (which closed on June 28, 2015).

Tremblay station is located south of Tremblay Road and directly west of the Via Rail station known as Ottawa station. The Ottawa station entrance is less than a five minute walk from the Confederation Line platforms on Level 1. While the stations are close to each other, the two buildings are not linked and transferring passengers are required to walk outside between them.

North of the station is the Max Keeping Pedestrian Bridge, which crosses Highway 417, allowing access to RCGT Park (a minor-league baseball stadium) as well as the Courtyard by Marriott Ottawa East and Hampton Inn by Hilton Ottawa west of the stadium parking lot. These two hotels are the closest to the station, and are linked to each other by the Ottawa Conference and Event Centre. All of these are accessible within a 12–15 minute walk.

Tremblay is a side platform station located at grade in a cutting. The station's single entrance building, located at the same level and opposite the railway station entrance, contains the ticket barrier and exits onto a plaza.

The station's artwork is entitled National Garden, an installation by Jyhling Lee. A series of canopies on the plaza outside the station entrance features silhouettes of flowering plants seemingly cut out of the reflective material of the canopy ceilings and folded down to produce a suspended garden.
