Pigeon Post is an English children's adventure novel by Arthur Ransome, published by Jonathan Cape in 1936. It was the sixth of twelve books Ransome completed in the Swallows and Amazons series (1930 to 1947). He won the inaugural Carnegie Medal from the Library Association, recognising it as the year's best children's book by a British subject.

Pigeon post is the use of homing pigeons to carry messages. Pigeons were effective as messengers due to their natural homing abilities. The pigeons were transported to a destination in cages, where they would be attached with messages, then naturally the pigeon would fly back to its home where the owner could read his mail. They have been used in many places around the world. Pigeons have also been used to great effect in military situations, and are in this case referred as war pigeon.
