AB Noncommutative spacetimes are widely believed to model some properties of the quantumstructure of spacetime at the Planck regime. In this contribution the construction of (anti)deSitter noncommutative spacetimes obtained through quantum groups is reviewed. In this approach the quantum deformation parameter z is related to a Planck scale, and the cosmological constant Lambda plays the role of a second deformation parameter of geometric nature, whose limit Lambda → 0 provides the corresponding noncommutative Minkowski spacetimes.
