A multi-viewing angle floating projection device including multiple directional light sources, a display panel and an imaging concave mirror is disclosed. The multiple directional light sources emit multiple directional light beams for illuminating the display panel to form multiple directional image beams. The multiple directional image beams are reflected by a reflector to the concave mirror. Then, the multiple directional image beams are respectively reflected by the concave mirror to multiple viewing areas with different viewing angles to form multiple floating projected real images. The illuminated regions of the multiple directional light beams on the display panel are almost the same, or the illuminated regions of the multiple directional image beams on the imaging concave mirror are almost the same, providing a larger viewing angle difference between the multiple viewing areas.
