We report CCD photometry of the cataclysmic variable star V1113 Cyg. During two campaigns, lasting from May to August 2003 and from March to June 2005, we recorded two superoutbursts. In the obtained light curves we detected clear superhumps with a mean period Psh=0.07891(3) days (113.63±0.04 min). That fact confirms that the star is a member of SU UMa class of dwarf novae. During the first observed superoutburst the superhump period was decreasing with an enormous rate of P=-4.5(8)×10-4 which is one of the highest values ever observed in SU UMa systems.
