Noncommutative gravity is a very interesting subject that has not yet been successfully related to string theory. However, it can be motivated by itself by the consideration of a description of the microscopic structure of spacetime, leaving for the future its precise connection to string theory or M-theory. In this paper we review some of the recent attempts to make sense of the noncommutative description of some classical theories of gravity by using the Seiberg-Witten map. In particular we describe noncommutative topological gravity and a gauge invariant proposal generalizing Plebanski-Ashtekar Self-dual gravity.

Palavras-chave : Noncommutative field theory; Seiberg-Witten map; topological gravity; self-dual gravity.
