Westminster station is a Regional Transportation District (RTD) commuter rail station on the B Line in Westminster, Colorado, part of the Denver metropolitan area. The station opened on July 25, 2016, and became the interim northern terminus of the B Line until extensions north toward Boulder and Longmont are built. From Westminster, B Line trains travel 6 miles (9.7 km) south to Union Station in Denver, taking about 11 minutes.

The station consists of a single platform on the north side is situated on the south side of the tracks. It will have a 350-stall park and ride that can be expanded to 1,000 spaces and a public plaza, both located on the north side of the tracks. The station is connected to the nearby Adams County residential neighborhood by a 165-foot-long (50 m) pedestrian bridge over the tracks, platform, and nearby Little Dry Creek. The underpass of the station, connecting to the north plaza, is home to a 90-foot-long (27 m) art installation by Brian W. Brush called "Grotto", which consists of high-density polyethylene plastic tubes lit by LED lights in an array of colors.

The City of Westminster plans to encourage transit-oriented development in a 135-acre (55 ha) area around the station; a 40-acre (16 ha) park and open space is also planned for the south side of the station area.
