Given a large graph $H$, does the binomial random graph $G(n,p)$ contain a copy of $H$ as an induced subgraph with high probability? This classical question has been studied extensively for various graphs $H$, going back to the study of the independence number of $G(n,p)$ by ErdH{o}s and Bollobas, and Matula in 1976. In this paper we prove an asymptotically best possible result for induced matchings by showing that if $C/nle p le 0.99$ for some large constant $C$, then $G(n,p)$ contains an induced matching of order approximately $2log_q(np)$, where $q= frac{1}{1-p}$.
