The EF 20-35mm f/3.5-4.5 USM lens is a wide-angle lens made by Canon Inc., with an EF mount.
It is a consumer grade lens, and as such has inferior quality (compared to comparable L-series lenses), but is cheap and light, and as such can be a good value.
[edit] EF 20-35mm f/2.8L
Formally, an f/2.8L existed, but that was replaced by the EF 17-35mm f/2.8L, which was in turn replaced by the EF 16-35mm f/2.8L USM.
