With the discovery of the faint embedded source L1014-IRS, the Spitzer Space Telescope has opened a new window for the study of very low mass objects and the formation of brown dwarfs. Using the Submillimeter Array we report the discovery of a compact low mass bipolar molecular outflow from L1014-IRS and confirm its association with the L1014 dense core at 200 pc. Consequently, L1014-IRS is the lowest luminosity (L ~0.09 L\odot) and perhaps the lowest mass source known to be driving a bipolar molecular outflow, which is one of the smallest known in size (~500 AU), mass (< 10-4 M\odot), and energetics (e.g., with a force < 10-7 M\odot km\,s-1 yr-1). These results suggest that L1014-IRS is either a very young protostar yet to accrete a significant fraction of its final mass, or will remain substellar, which would suggest that brown dwarfs can form in a manner broadly similiar to low mass stars.
