This article is about a molecular dynamics program. For more meanings of the word Orac, see ORAC.

Orac is a classical molecular dynamics computer program (written in FORTRAN language) for simulating complex molecular systems at the atomistic level. The code was written originally in 1989-90 by Massimo Marchi during his stay at IBM, Kingston (USA). The code was further developed at CECAM in 1995 and released under the GPL license in 1997.[1] The latest release [2] of Orac may be run in parallel using the standard Message Passing Interface libraries, allowing replica exchange simulations, multiple walkers metadynamics[3] simulations and multiple steered molecular dynamics[4] nonequilibrium trajectories.
