This study looks at how artificial intelligence (AI) might change teacher education in Nigeria by boosting administrative effectiveness, improving assessment and classroom practices, strengthening professional development, and personalizing teacher learning.  It maps opportunities (adaptive learning tools, automated feedback, content generation, data-driven decision-making) and challenges (digital infrastructure gaps, teacher readiness, ethical risks, policy and regulatory lacunae) based on policy documents, international guidance, and recent empirical studies.  In order to generate practical suggestions for legislators, teacher educators, and development partners, the study employs a qualitative synthesis of secondary literature and policy analysis.  Important suggestions include incorporating AI literacy into teacher preparation, testing professional development initiatives powered by AI, bolstering digital infrastructure and data governance, and implementing moral standards in line with national and UNESCO policies. The study concludes that AI can be a catalytic force in teacher education in Nigeria but only if investments align with capacity building, inclusivity, and robust governance.
