Prerasts of Vratna (Serbian: Прерасти Вратне, or Vratna Gates (Serbian: Вратњанске капије) are three natural stone bridges, two in the vicinity of the medieval Vratna monastery, and the third farther away into the depths of the Vratna river gorge, in Bor, Eastern Serbia. They are entered through marked hiking trails, which was through monastic property. Nowadays trail go around monastic land and leads beneath first Vratna Gate or Little Prerast.

Prerast (see ) in Serbian means "outgrowth" or "overgrowth." In this case it is an unambiguous term by the local population for these types of natural rock bridges, vaults and gates.

The Prerasts of Vratna are of different origins. While the first two are remains of a former cave tunnel through witch river Vratna ran through, and part of the arch between them collapsed, the third resulted from the plunging of the river. In the vicinity was discovered examples of karst terrain, three unexplored caves, one of which is the longest, the second is rich in tunnels and corridors, and in the third has a small lake.
