  We expect that at least one Gamma-Ray Burst per month will be detected in the
field of view of INTEGRAL instruments and localized with an accuracy of a few
arcminutes. IBIS (the Imager on board INTEGRAL) will be the most sensitive
instrument in the soft $\gamma$-ray band during the next few years. This will
allow INTEGRAL to detect the faintest (and hence the most distant) $\gamma$-ray
bursts, thus surely contributing to the study of the physics of GRBs and to the
comprehension of the early stages of the Universe. GRBs will be detected and
localized in (near) real time with the IBAS (INTEGRAL Burst Alert System)
software, and their coordinates will be immediately distributed to the
scientific community, allowing for prompt follow-up observations at other
wavelengths. The flexibility of the IBAS software, running on ground at the
ISDC, will allow us to possibly reveal new classes of bursts, such as
ultra-short bursts ($\sim$ ms) or very long (t $>$ 50 s) but slowly rising
bursts, that could not be detected by previous experiments.
