The Lechtal Alps (German: Lechtaler Alpen) are a mountain-range in western Austria, and part of the greater Northern Limestone Alps range. Named for the river Lech which drains them north-ward into Germany, the Lechtal Alps occupy the Austrian states of Tyrol and Vorarlberg and are known for their diverse rock structures.

The Lechtal Alps are surrounded by the Ötztal Alps , Samnaun Alps and Verwall Alps (south) and the Allgäu Alps (north).
