The Stuttgart–Wendlingen high-speed railway is an under construction German high-speed line being built as part of the Stuttgart 21 project. It runs from Stuttgart Hauptbahnhof via the Filder Tunnel to the Filder plain and from there to the Neckar valley at Wendlingen, where it runs on to the Wendlingen–Ulm high-speed line. It is part of the Paris-Bratislava corridor as defined by the European Union.

The line will connect the new Filder station via the Airport Loop, and another line will connect to the existing airport station.

The design speed of the approximately 25.2 km line is mostly 250 km/h (155 mph). As of 2024, it is planned to enter in commercial service in December 2026 (two years delay compared to the expectation from 2017).
