The Boßler Tunnel is a railway tunnel currently under construction as part of the new Wendlingen–Ulm high-speed railway. The tunnel is approximately 8,806 metres (28,891 ft) long, built as two parallel single-track tunnels. 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. When completed, it will be 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).
The north-west portal (portal Aichelberg, track location marker 39.720 km, 48°37′50″N 9°33′50″E / 48.6305°N 9.5640°E), situated northeast of Weilheim an der Teck, is the border of one of the line's planning sections. The line approaches this portal from the west, parallel to the A8 motorway.
The tunnel runs in a straight line towards the southeast, passing under the Roter Wasen and the Boßler. The tunnel climbs about 213 metres (699 ft) to the southeast portal, with a gradient of about 25‰ (1 in 40). The maximum overburden depth is 280 metres (920 ft).
