The Boßler Tunnel is a 8,806 m long railway tunnel on the Wendlingen–Ulm high-speed railway. It is built as two parallel single-track tunnels between the 45.367 to 54.175 km mark. The tunnel runs between Aichelberg and Mühlhausen im Täle under the Roter Wasen and the Boßler mountain. It is one of a series of tunnels underneath the Swabian Jura range. It is the longest tunnel on the line and the fifth longest tunnel in Germany (after the Landrücken Tunnel, the Münden Tunnel, the Filder Tunnel and the Katzenberg Tunnel).
