The windshield or windscreen of an aircraft, automobile, or motorcycle, is the front window. Modern windshields are generally made of two sheets of curved glass with a plastic layer laminated between them for safety. Windshields protect the vehicle's occupants from wind, temperature extremes, and flying debris such as dust, insects, and rocks.

In many places, laws restrict the use of heavily tinted glass in vehicle windshields; generally, laws specific the maximum level of tint permitted.

In aircraft windscreens a current is applied through a conducting layer of tin(IV) oxide to generate heat to prevent frost.
