The variable star V1735 Cyg (= Elias 1-12) is located in the IC 5146 dark cloud, a region of active low-mass star formation that has been extensively studied in the optical and infrared. We present results of an X-ray observation of IC 5146 with XMM-Newton, centered on V1735 Cyg. This star is a member of the class of FU Orionis variables that undergo strong optical outbursts thought to be linked to episodic accretion. Hard X-ray emission was detected from V1735 Cyg at a characteristic temperature kT > 5 keV, in some respects similar to that recently detected in the prototype FU Ori (Skinner et al. 2006, ApJ, 643, 995). We compare the X-ray properties of V1735 Cyg and FU Ori and discuss possible emission mechanisms in the framework of a complex physical environment that likely involves accretion, strong winds, magnetic fields, and possible binarity. We also report the discovery of a second
X-ray source located 24 arc-secs northeast of V1735 Cyg that may be associated with a deeply embedded young star previously detected in sub-mm observations.
