An 8.4 GHz VLA survey of 91 recently discovered T Tauri stars from the ROSAT All-Sky Survey and pointed observations is presented. These objects lie in the vicinity of the Taurus-Auriga star-forming region (d =~ 140 pc), however some are dispersed nearly 30(deg) from known active star-forming cloud cores. This sample represents a spatially-complete, flux-limited population of X-ray bright T Tauri stars both within and away from the primary Tau-Aur stellar nurseries. Of the 91 sources, 17-29 are detected in this radio survey with a sensitivity limit of ~ 0.15 mJy. Hence 19-32% of widely distributed T Tauri stars with LX >= 5x10(28) ergs s(-1) have radio luminosity densities in excess of 3.5x10(15) erg s(-1) Hz(-1) . This detection rate and range of radio and X-ray luminosities are consistent with known young weak-lined T Tauri stars (ages ~ 10(6) ) yr) which reside within the Taurus molecular clouds, but is considerably higher than a ZAMS population such as the Pleiades (age =~ 7x10(7) yr). These T Tauri stars fit well among other active young stars on the empirical LR vs. LX diagram, implying that solar type gyrosynchrotron activity is the radio emission mechanism.
