The Wehra Valley Railway (German: Wehratalbahn) was a 19.7 km long branch line from Schopfheim to Bad Säckingen in southwestern Germany, that was electrified in 1913 at the same time as the Wiesen Valley Railway.

Goods traffic between Bad Säckingen and Wehr continued to run until 1 September 1990.

In a local council meeting on 19 April 2005, the town of Wehr (Baden) called for an expert opinion to determine whether the line could be reactivated.

The report from Tübingen-based local transport advisor Ulrich Grosse was positive, although its restoration would be relatively expensive and only possible for a short time.

Currently checks are being carried out to see whether the Fahrnau Tunnel can be reopened.
