Not that we know of.


Plate tectonics is a very recent discovery. It is at is core a serious of large individual solid plates floating on the earth's liquid core. We know Mercury and Mars are "dead" planets because they have no volcanic activity which is the necessary piece to plate tectonics. Venus is still mostly a mystery because of it being shrouded in clouds and the limited access to its surface we have had.

The rest of the planets are what are called "gas planets" which means they have no molten rock at their core. Their is a possibility that one or more of Jupiter's moons has volcanic activity which could mean they also have plate tectonics but none of this has yet be verified.
