Public school teachers are instructed by the government to teach science subjects through English at secondary schools, which is not less than a nightmare for teachers. Their poor language skills enhance their level of anxiety while teaching through English which ultimately affect the student' motivation. This study aimed to investigate the relationship between language anxiety in teaching science and students' motivation at secondary schools. A quantitative research methodology was adopted to conduct this study. A convenient sampling technique was adopted to collect data from secondary school teachers and students. Simple linear regression and independentsample t-test were applied to analyze data. As to findings, it is identified that teachers' language anxiety has no impact on students' level of motivation. As to language anxiety, both male and female teachers perceived equal level of anxiety. Whereas the difference between boys and girls in relation to their perceived motivation was significant. The discussion highlighted these strange results with the help of available researches.
