Sir John Valentine Carden, 6th Baronet MBE (6 February 1892 – 10 December 1935) was an English tank and vehicle designer.
During the First World War, Carden served in the Army Service Corps and gained the rank of captain, acquiring experience with vehicles such as tracked Holt tractors.
After the war, he returned to car manufacturing but sold his original design and factory to Ward and Avey who renamed it the AV.
Carden's interest in flying also led him to build an ultralight plane based on the French "Flying Flea", using a modified Ford engine uprated from 10 bhp to 31 bhp.
John Carden was killed in an air crash near Tatsfield, Surrey on 10 December 1935, while flying on a Sabena airliner.
