Marlborough Station is a Calgary C-Train light rail station in the Calgary Northeast neighbourhood of Marlborough. It serves the Northeast Leg of the Blue Line and opened on April 27, 1985, as part of the original Northeast (202) line.

The station is located in the median of 36 Street NE, located near its intersection with 8 Avenue NE/Marlborough Drive NE. The station is 6.5 km (4.0 mi) from the City Hall Interlocking and is located near Calgary's Marlborough neighbourhood and also serves nearby businesses along 36 Street NE, including Marlborough Mall. Pedestrian overpasses connect the station to both sides of 36 Street NE. Stairs, escalators, as well as an elevator provide access down to the center-loading platform. 485 spaces of the mall facility are now owned by Calgary Transit and are designated for park-and-ride service.

In 2005, the station registered an average transit of 19,600 boardings per weekday, the busiest station in the system other than the downtown platforms.

As part of Calgary Transit's plan to operate 4-car trains by the end of 2014, all 3-car platforms have been extended. Marlborough station saw new furnishings in addition to a platform extension. Construction started in the late Summer of 2013, and was finished in January 2014.

Calgary Transit, in collaboration with Shaw Communications, announced on November 16, 2016, that 8 new locations for Public Wi-Fi services would be added to the Calgary C-Train system. These new locations would add public Wi-Fi to 18 new stations; including Marlborough Station. These changes were done as they would improve transit experience for their users, which would improve customer commitment.

As part of station upgrades with Marlborough along with Rundle, the interiors of the two stations were renovated starting in June 2016 and finishing in December 2017. This was to bring the two stations up to the same standard as Whitehorn Station which was renovated in 2011. These renovations would include: modifications to the stations layout to improve traffic such as changing the location of the elevators, replacement of the escalators and removal of the 'down' escalator, improvement and increasing of security cameras, upgraded heating and ventilation. These changes would also come with a complete overhaul of the interior design of the two stations, coming with a new modernistic design that was generally cleaner and less dated (in comparison to the old design which featured gothic designs, with heavy use of bricks and was overall dark and dimly lit).
