Carleton is a light rail station located along the Trillium Line at Carleton University in Ottawa, Ontario.

Carleton is currently the only O-Train station along the Trillium Line with separate tracks and platforms for each direction, in order to allow the two trains working the otherwise single-track line at any given time to pass. The schedule is timed such that the southbound train arrives first and moves onto the platform siding, and then proceeds once the northbound train has entered the station.

North of Carleton, the train heads into a tunnel under the Rideau Canal. South of Carleton, the train crosses over the Rideau River on a bridge. As part of the Stage 2 South expansion, the southernmost pedestrian underpass linking Richcraft Hall and Pigiarvik was rehabilitated, and the main pedestrian underpass located between the station platforms and the Maintenance Building was demolished and replaced with a new structure double the length of the original. As part of Stage 2 South, a tunnel spur was constructed underneath the station footprint, which in the near-to-medium-term future could provide a direct, weather-protected connection between the station and the Carleton University tunnel system, though semantics are unknown at this point. In the 2023 Campus Master Plan update, the university included plans to build a transit hub on the eastern side of the station, which would result in the decommissioning of the existing parking lot and the relocation of all bus connections and bus–train transfers to that area. Pending approval by the City of Ottawa, Carleton plans to connect the transit hub directly to the northbound platform of the train station, providing an additional fare-paid access point for the community.
