The Lake Thun railway line is a railway line in the Swiss canton of Bern. It links the towns of Thun, Spiez and Interlaken, running principally along the southern shore of Lake Thun. The line was opened in 1893 by the Lake Thun Railway (German: Thunerseebahn, TSB) company, but incorporates much of the earlier Bödeli Railway (German: Bödelibahn) dating back to 1872.

The line is 27.9-kilometre (17.3 mi) long, and is currently owned and operated by the BLS AG railway company. Besides traffic to and from Interlaken, the section of line between Thun and Spiez also carries heavy traffic to and from the Lötschberg line.

The history of the Lake Thun line is linked to that of the shipping services on Lake Thun and Lake Brienz, which date back to at least 1834, when the first steamship was introduced. The two lakes are linked by a 5.5 km (3.4 mi) stretch of the Aare through Interlaken, but the river is not navigable, dropping some 6 metres (20 ft) and passing over several weirs.

In 1872, the first part of the Bödeli Railway was built, from Därligen, on Lake Thun, to what is now Interlaken West station. In 1874, it was extended, via what is now Interlaken Ost station, to Bönigen, on Lake Brienz. The line was not connected to any other railway, and served to connect the shipping on the two lakes to each other, and to Interlaken. The route of the Bödeli Railway crosses the Aare twice, using bridges with little headroom beneath them, and it has been suggested that this was done deliberately in order to dissuade attempts to canalise the river and thus maintain the railway's role.
