The invention relates to a collapsible scaffold platform (10). The scaffold platform (10) has a first scaffold platform body (22) and a second scaffold platform body (24). The scaffold platform bodies (22, 24) are connected together by means of a hinge (28). The hinge (28) enables the scaffold platform (10) to be collapsed for assembly, disassembly and transport. The width of the scaffold platform (10) is reduced in the collapsed state. Preferably, the width of the scaffold platform (10) is halved in the collapsed state. Preferably, each scaffold platform body (22, 24) has connecting means on each end face, as viewed in the longitudinal direction of the scaffold platform (10), in particular in the form of hooks (20), for connecting the scaffold platform (10) to crossbars (50, 56) of a scaffold (44). More preferably, the scaffold platform (10) has a lift-off safety lock (32, 34) on each end face, as viewed in the longitudinal direction. The lift-off safety locks (32, 34) are preferably arranged diagonally to one another such that, in the collapsed state of the scaffold platform (10), only a first lift-off safety lock (32) locks the scaffold platform (10) on a first cross bar (50). The invention further relates to a scaffold (44) comprising such a scaffold platform (10).
