可变后掠翼（Variable-sweep wing）是一种可随不同飞行情况而改变掠角的设计。这样的设计可以同时利用后掠翼在高速以及直线机翼在低速下的优点。然而这种设计却增加了飞机的重量和增加结构复杂度。另外一种常见的称法是可变几何翼面（Variable-geometry wing）。

A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be swept back and then returned to its original position during flight. It allows the aircraft's shape to be modified in flight, and is therefore an example of a variable-geometry aircraft.
