The Sihltal railway line (German: Sihltalbahn) is a railway line in the Swiss canton of Zürich, which connects the city of Zürich with the communities of the Sihl Valley. Passenger service on the line now forms part of the Zürich S-Bahn, branded as that network's service S4, and is part of the Zürcher Verkehrsverbund (ZVV) zone-based fare network.^[2][3]

The line was opened in 1892 and electrified in 1924. Today it is owned by the Sihltal Zürich Uetliberg Bahn SZU AG, a company that also owns the Uetliberg line, and organizes the Zimmerberg Bus, and operates the Luftseilbahn Adliswil-Felsenegg (LAF).^[4]
