The R Line or Aurora Line/I-225 Rail is a Regional Transportation District (RTD) light rail line that serves stations in Aurora, Denver, Greenwood Village, Centennial and Lone Tree. Opening on February 24, 2017, the line was designated as the "R" line, reflecting the letter R’s in "Aurora" and "RidgeGate".

The line travels over newer and older portions of the RTD Light Rail system. The R Line was preceded by the G Line, which operated from 2006 to 2009 along the southern half of the route. The R Line is the only line in the RTD rail system not serving downtown Denver.

Service south of Florida station was suspended from June 2023 until October 2023 due to maintenance on the Southeast Corridor between I-25 & Broadway station and Lincoln station. This project is temporarily paused until May 2024. The R Line is and will continue running the full route between Peoria and Lincoln; however, it will see limited service in the evenings throughout the rest of the project.
