An illumination system including a light integration rod, light source modules and a light guide element is provided. The light integration rod has a light incident end and a light exit end. The light source modules are disposed adjacent to the light incident end, and each light source module is suitable for providing a converging light beam. The light guide element is disposed adjacent to the light incident end and between the light source modules for guiding each light beam to be incident to the light integration rod. The optical axes of the light beams are parallel to each other and a distance exists between any two optical axes of the light beams. The light beams are combined inside the light integration rod and emitted from the light exit end to provide an illumination beam. Moreover, a projection apparatus having the illumination system is provided.
