The G Line is a Regional Transportation District (RTD) commuter rail line that serves stations in Denver, Arvada, and Wheat Ridge, Colorado. The G Line opened on April 26, 2019, is owned by RTD, and is operated by Denver Transit Partners. During planning and construction, it was also known as the Gold Line. It is colored gold on system maps.

The G Line's eastern terminus is at Union Station in downtown Denver, and its western terminus is at Ward Road in Wheat Ridge. Despite the line's letter name and color being a partial reference to the city of Golden, the G Line does not serve it as of 2026.
