This volume presents the revised lecture notes of selected talks given at the Third Central European Functional Programming School, CEFP 2009, held in May 2009 in Komárno, Slovakia. It was co-organized with the TFP 2009 conference. The summer school included a three days warm-up session organized in Budapest, Hungary also in May, 2009. The 11 revised full papers presented were carefully reviewed and selected. The lectures cover a wide range of topics such as design patterns, semantics, types, and advanced programming in various functional programming languages.
