This study focused on teachers' academic self-concept and academic stress as predictors of academic achievement of Biology students' in Enugu Education Zone. Six (6) null hypotheses were postulated for the study. The study adopted ex-post-facto research design. The population of study comprised 74 Biology teachers in 33 public secondary schools in Enugu Education Zone with SS 2 biology students' population of 4,737. The sample consisted of all the Biology teachers' in the Zone and a sample of 10% of the students' were sampled from the Biology teachers' classroom. The instrument used for data collection were three (3) Marsh teachers' academic self-concept scale, Balamurugau and Kumaran academic stress scale and Students' scores from their promotion examination 2022/2023 academic year were used to measure their academic achievement in Biology. The instruments were validated by three experts and the internal consistency reliability was determined though Cronbach Alpha method. The teachers' self-concept scale yielded a reliability index of 0.92 while teachers' academic stress scale yielded an index of 0.88 coefficients. The data collected were analysed using Simple and multiple regression analysis with Statistical Package for Social Sciences (SPSS) version 22. The findings of the study showed that: Teacher academic self-concept significantly and positively predicted students' academic achievement in Biology in Enugu Education Zone; likewise, teachers' academic stress significantly and negatively predicted students' academic achievement in Biology in Enugu Education Zone. Based on these findings it was recommended amongst others that Biology teachers should arrange learning activities, in such a way that it will help students to be self-directed in their learning in order to have significantly positive achievement in Biology.
