Limited studies have been conducted on the effects on recreational reading in native language on foreign language learning, whereas no findings exist on the effects of recreational reading in Turkish as a native language (L1) on English as a foreign language (EFL) learning. Thus, this study aims to investigate the effects of recreational reading in L1 on the process of learning EFL. The sample group consists of 70 learners and a background questionnaire, interviews, oral presentations, classroom discussions, essay papers, and responses to examination questions were used for data collection. The results indicated that recreational reading in L1 has some significant contributions to EFL learning although it has some negative effects. (Contains 1 figure.)
