Multi-body $D^0$ decays provide important insights into the phenomenon of charm mixing as some of those observables are complementary to those from two-body decay modes. In these multi-body channels, the interference between different resonant contributions can be exploited using either model-dependent or model-independent methods to determine the mixing parameters $x$ and $y$. In this contribution, the latest results on charm mixing from multi-body decays from LHCb are presented.
