We consider the space of meromorphic functions in the unit disk 𝔻 and show that there exists a dense G δ -subset of functions having universal radial limits. Our results complement known statements about holomorphic functions and further imply the existence of meromorphic functions having maximal cluster sets along certain subsets of 𝔻.
