Short-range experiments testing the gravitational inverse-square law at the submillimeter scale offer uniquely sensitive probes of Lorentz invariance. A combined analysis of results from the short-range gravity experiments HUST-2015, HUST-2011, IU-2012, and IU-2002 permits the first independent measurements of the 14 nonrelativistic coefficients for Lorentz violation in the pure-gravity sector at the

level of 10−9 m2, improving by an order of magnitude the sensitivity to numerous types of Lorentz

violation involving quadratic curvature derivatives and curvature couplings.
