We summarize the current status of numerical relativity for higher-dimensional spacetimes. In the first part, the ingredients necessary for successful simulations developed to date are summarized, including formulations, methods of implementing spacetime symmetries, and gauge conditions. In the second part, we review the simulations performed so far, such as time evolution of a black string that is unstable against the Gregory-Laflamme instability, black hole collisions and scatterings, and time evolution of rapidly rotating Myers-Perry (MP) black holes with one rotational parameter which are unstable against bar-mode deformation. The remaining issues and expected future developments are briefly described.
