This Letter reports the results of very deep near-infrared imaging of the core of the star-forming Bok globule B335 in H, K, and 2.12 mu m H2 nu =1-0 S(1) line emission. The outflow cavity associated with the class 0 protostar embedded in B335 and features in the blueshifted outflow lobe are detected in the deep K-band images, mostly by emission from shock-excited molecular hydrogen. Only extremely faint traces of the outflow are seen in the H band. Several knots of S(1) emission are found near the edge of the globule on either side of the outflow. The cloud core is outlined in absorption against diffuse H- and K-band flux in B335, presumably scattered starlight.
