The All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer has been scanning the sky to roughly a sensitivity of 20 mCrab in the 2-12 keV band for over two years since its activation in January 1996. In addition to studying the behavior of X-ray binaries, it has serendipitously observed a gamma-ray bursts (GRBs) roughly once every two months. I will outline the effort by the ASM team to quickly identify (within two hours) and accurately locate (to within a few arcminute radius) these elusive transients in conjunction with BATSE, BeppoSAX and the IPN. I will present the ~ 12 GRBs we have identified in our database thus far, and compare the ASM observations of some bursts with later observations of faint afterglow by other missions where such data are available.
