We discuss how the fine‐tuning of the cosmological constant enters brane world setups. After presenting the Randall Sundrum model as a prototype case, we focus on single brane models with curvature singularities which are separated from the brane in the additional dimension. Finally, the issue of the existence of nearby curved solutions is addressed.
