Due to the high suppression of $s\rightarrow d$ transitions, the sector of rare strange decays is a particularly powerful probe for New Physics. Assuming non-minimal flavour-violation, bounds from strange decays go up to a scale of $\mathcal{O}\left(10^5\right)\text{TeV}$. Taking advantage of the high production rate of strange hadrons at the LHC, the LHCb detector is able to perform competitive measurements on decays like $K_S^0\rightarrow\mu^+\mu^-$, $\Sigma^+\rightarrow p\mu^+\mu^-$, $K_S^0\rightarrow\pi^0\mu^+\mu^-$ or $K_S^0\rightarrow l^+l^-l^+l^-$. These proceedings summarize recent results on searches for rare strange decays by the LHCb collaboration.
