We present resolved images of the dust continuum emission from the debrisdisk around the young (80-200 Myr) solar-type star HD 107146 with CARMA at$\lambda$1.3 mm and the CSO at $\lambda$350 $\mu$m. Both images show that thedust emission extends over an $\sim$10\arcsec diameter region. The highresolution (3\arcsec) CARMA image further reveals that the dust is distributedin a partial ring with significant decrease in flux inward of 97 AU. Twoprominent emission peaks appear within the ring separated by $\sim$140 degreesin position angle. The morphology of the dust emission is suggestive of dustcaptured into a mean motion resonance, which would imply the presence of aplanet at an orbital radius of $\sim$45-75 AU.
