A baseball water slide apparatus includes a panel that has a top side and a peripheral edge. The panel is flexible and has a substantially square shape. A loop member is attached to the top side. The loop member is hollow and defines a tube. The loop member is positioned adjacent to and extends along the peripheral edge of the panel. The loop member has a plurality of apertures extending through that are each directed generally inward of the panel. An inlet hose is fluidly coupled to the loop member. A water supply may be removably coupled to the inlet hose such that water may be supplied to the loop member. A plurality of bases is attached to the top side of the panel. Each of the bases is positioned adjacent to one of four corners of the panel.
