With the widespread use of English, the function of English has been shifted. English is now used as a lingua franca. This study aimed to explore students' attitudes towards English pronunciation models in English as a lingua franca (ELF). The students' attitudes towards their desired English pronunciation models and their interlocutor's pronunciation models were also examined. The participants of the research were 146 undergraduate students majoring in English. The research instrument was a questionnaire. The questionnaire elicited perceptions regarding students' degree of favor or disfavor towards nine English pronunciation models selected from three Kachru's concentric circles, and their attitudes towards their English pronunciation models. The findings of this study revealed that the participants had moderate attitudes towards their desired English pronunciation models, and their interlocutor's English pronunciation models. However, the participants had negative attitudes towards English as a lingua franca. That is, the participants had highly positive attitudes towards American English and British English pronunciation models. They also believed that maintaining their Thai English pronunciation model was not important. This may have resulted from the participants' limited of exposure to other English varieties, the entrenched native ideology, and the participants' lack of awareness of other English varieties.Index Terms-Attitudes, English as a lingua franca (ELF), English pronunciation models.
