Anything with a Canon EOS mount will fit on your camera, including EF and EF-S lenses. Older third party lenses *Sigma, Tamron, Tokina) will fit, but may not work, so be careful if you are buying used. Canon changed the way the camera and lens talk to each other about 7 years ago and since the 3rd party guys reverse engineer Canon's connections, their lenses were not compatible.

The instructions that came with your camera CLEARLY explains what lenses can be used.

EF or EF-S mount lenses are all compatible with your Rebel.
