There is a growing body of work utilising N-body simulations with alternative gravity theories, but simulations at a galactic scale remain a relatively unexplored area. In this work, we present the first simulated galaxy rotation curves under f(R) gravity to our knowledge. The f(R) gravity solver MG-GADGET (Puchwein et al. 2013) is employed statically on pre-simulated spiral galaxies, leading to solutions for the rotation curves and screening radii under HuSawicki f(R) gravity. It is shown that under certain parameter regimes, the so-called 'fifth force' yields observable signatures, which can be exploited to constrain departures from classical gravity.
