Clinamen is the name Lucretius gave to the spontaneous microscopic swerving of atoms from a vertical path as they fall ^{(1, lines 216-293)}. According to Lucretius, there would be no contact between atoms without the clinamen, and so, "No collision would take place and no impact of atom upon atom would be created. Thus nature would never have created anything." ^{(lines 220-225)} This was first described in Epicurian physics.

The clinamen has been taken up in discussions of determinism as a possible explanation for an incompatibilist free will.

The term has also been taken up by Harold Bloom to describe the inclinations of writers to the influence of their predecessors.
