Private Joe Walker is a fictional black market spiv (or Wholesales Supplier, as he politely puts it) and Home Guard platoon member, first portrayed by actor James Beck in the BBC television sitcom Dad's Army. In real life, Beck died suddenly on 6 August 1973. The character of Walker was one of the seven primary characters in the show. Following his character's departure (Walker was last mentioned in the episode "The Recruit", although he does not appear in this episode) the series attempted to replace him with a war reporter called Private Cheeseman (played by Talfryn Thomas), who had made a previous cameo appearance in the episode "My British Buddy".

He is constantly on the lookout for opportunities to make a few bob, and can normally be found trying to sell such things as petrol coupons and black market foodstuffs to his platoon comrades, usually at high prices and from dubious sources. His "business" activities are not limited to just the members of the platoon, or indeed even to the residents of Walmington-on-Sea, as he has often made reference to acquiring "essential supplies" for members of the rival Eastgate platoon and various influential people, military or civilian; at one point, he offers to provide "a couple of bottles of scotch" to a high-ranking GHQ officer, when Mainwaring briefly loses his command of the platoon. Indeed, the only time Walker can't find a buyer for his
