Quincannon, Frontier Scout is a 1956 American Western film directed by Lesley Selander and written by John C. Higgins and Don Martin.

His former commanding officer, Colonel Conover, calls him back to duty to help him solve the mystery of how the Arapahoes had learned of a secret shipment of Henry repeating rifles and ammunition intended to arm the troopers of his regiment, and stolen them.

Things are complicated by the presence of Maylene Mason, a spirited blonde from the East who has come to the frontier to determine the fate of her brother, who was probably killed during the raid in which the rifles were stolen.

The Crows warn Quincannon the Arapahos are on the warpath and hoping to make common cause with the Sioux and the Cheyenne to start a major war.

Quincannon, Burke, and Calvin do some quiet investigating, and discover that Bell's second-in-command, Lieutenant Hostedder, is in possession of $2,000 in gold coins stolen from an Army paymaster by the Arapahoes.

Bell brings Hostedder to his office to "question" him – the two of them were in cahoots with an Arapaho chief, Iron Wolf, who stole the rifles to become the leader of the rebellious tribes – and murders him before he can squeal.

Leaving Maylene at Fort Bell, Quincannon, Burke, and Calvin go in search of a fur trader and whiskey peddler, Blackfoot Sam, who may give them an "in" with the tribes who are on the warpath.

With Quinny now in a position to afford a bride, Maylene asks him if she is still worth twenty fine ponies, and he accepts her proposal by passionately kissing her.
