A ladder apparatus adapted for a scaffold is disclosed. The ladder apparatus includes a ladder, two top connection components disposed at a top of the ladder, two bottom connection components disposed at a bottom of the ladder, and two platform assemblies connecting the ladder. The ladder includes two lateral rails and a plurality of step shelves arranged between the rails. Each platform assembly has a platform, two fasteners connected respectively to opposite ends of an external side of the platform, two straddlers connected respectively to opposite ends of an internal side of the platform, and two retainers protruding respectively from two lateral sides of the platform. The ladder connects the internal sides of the two platform assemblies via the top and bottom connection components respectively. The platform assemblies stride over and are against two lateral stringers of the scaffold via the straddlers and join the scaffold via the fasteners. Hence, the top and bottom of the ladder apparatus are served as stages for operators standing on and doing construction jobs.
