We present the results of XMM-Newton observations in direction to the pulsar PSR J1826-1256, which lies at 5.4~arcmin from the centroid of the TeV source HESS~J1826-130. These data reveal an elongated nebula with the pulsar located in the northern border and a trail towards the peak of the very high energy source. The spectral analysis shows a nonthermal nature for the X-ray emission and a clear softening of the photon index with increasing distance from the pulsar. We discuss the connection among the pulsar, its nebula, and the HESS source.
