The gamma-ray source HESS J1837-069 was discovered during the first scan of the galactic plane, and was classified as an unidentified source, possibly associated with AX J1838.0-0655. Recently, an energetic 23 kyr pulsar was discovered in coincidence with the ASCA source. We present a preliminary analysis of a larger HESS data set which reveals finer morphology and spectral details. We discuss the pulsar wind nebula (PWN) interpretation of the gamma-ray source in view of the characteristics of other very high energy (VHE) emitting pulsar wind nebula.
