Molecular hydrogen narrow band imaging revealed a cluster of 4, or probably 5, highly collimated H2 emission jets and many isolated H2 emission knots in the NGC 2264 IRS1 region. Jets 1 and 2 each consists of 1 bright and 2 faint knots. Jet 2 is shifted towards northeast relative to jet 1, therefore, they are probably two distinct flows. Jet 3 is a short jet and jet 4 consists of 1 bright knot and several faint knots. Knots may constitute the fifth jet in the region. The relationship between these infrared outflows and the millimeter and submillimeter sources in the region, NGC 2264 MMS1-5, is discussed. Our detection of infrared outflows suggests that MMS1-5 are all in the protostar stage of their evolution. The high collimation of jets 1–4 may have important implication for the formation of intermediate and high mass stars.
