We present subarcsecond resolution mid infrared images of NGC 4151 at 10.8micron and 18.2 micron. These images were taken with the University of Floridamid-IR camera/spectrometer OSCIR at the Gemini North 8-m telescope. We resolveemission at both 10.8 micron and 18.2 micron extending ~ 3.5" across at a P.A.of ~ 60 degrees. This coincides with the the narrow line region of NGC 4151 asobserved in [OIII] by the Hubble Space Telescope. The most likely explanationfor this extended mid-IR emission is dust in the narrow line region heated by acentral engine. We find no extended emission associated with the proposed torusand place an upper limit on its mid-IR size of less than or equal to ~ 35 pc.Comment: accepted for publication in the Astrophysical Journal, 19 pages  including 5 figure
