The Lake Zurich left bank railway line, or Linksufrige Zürichseebahn, is a railway line in the Swiss canton of Zurich. As its name suggests, it runs down the left, or west, bank of Lake Zurich, connecting Zurich to Ziegelbrücke and Näfels.

The left bank railway forms part of the Zurich to Chur main line. Between Zurich and Thalwil, the line originally shared its tracks with the Zurich to Lucerne main line, although many through trains on this stretch now use the Zimmerberg Base Tunnel rather than the lakeside line.

The line was opened in 1875. Prior to this, trains between Zurich and Chur travelled on the Wallisellen to Rapperswil via Uster line. The parallel line on the opposite bank of Lake Zurich did not open until 1894.
