Stellar occultations have been used to search for Kuiper Belt and Oort Cloud objects. We propose a search for interstellar objects based on the characteristic durations (∼0.1s) of their stellar occultation signals and high inclination relative to the ecliptic plane. An all-sky monitoring program of ∼2×107 stars with an R-band magnitude of 14 using 1-m telescopes with 0.1s cadences, is predicted to discover ≳5 interstellar objects per year.
