A time resolved spectroscopic study of the SU UMa subtype dwarf nova AK Cancri is presented. An orbital period of P_orb=0.0651(2)d and a radial velocity half-amplitude of K=50(3)km/s were obtained from the radial velocity variations of the Hα emission line. Assuming various observational constraints, we deduced a most likely mass ratio of q=0.28±0.02 and stellar masses of M(1)=0.41±0.03M_☉ and M(2)=0.1135±0.0002M_☉, for the primary and secondary star, respectively. In addition, the dynamical solution indicates a low orbital inclination (i=36±3°).
