Officers investigating the incident say the smash happened around noon, when a Mercedes, Mini, Land Rover and a lorry collided between the junctions with Tonbridge Road and Old Church Road.
A man in his 50s from the Tunbridge Wells area was pronounced deceased at the scene. His next of kin have been informed.
A second man was treated for injuries and was taken to hospital for further medical attention.
Kent Police’s Serious Collision Investigation Unit say they are appealing for any witnesses to get in contact.
They are particularly keen to trace the driver of a white van who was near the scene at the time of the collision and may have important information.
Officers would also like to obtain CCTV or dash cam footage that shows the vehicles in the moments leading up to the collision.
