A flexible waterproof flying disc comprises a generally disc-shaped body terminating at its periphery in a downwardly extending rim. The body and the rim define a substantially convex upper surface and a substantially concave lower surface. The body has a core formed from a single piece of flexible, close, water-impervious cellular material and has at least one binding strip connected to and around a peripheral edge of the core for imparting a prestressed curvature to the core to define the convex and concave upper and lower surfaces, respectively.
