Noncommutative spacetimes are widely believed to model some properties of the
quantum structure of spacetime at the Planck regime. In this contribution the construction
of (anti-)de Sitter 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 Λ plays the role of a second deformation parameter of geometric nature,
whose limit Λ → 0 provides the corresponding noncommutative Minkowski spacetimes.
