Purpose: The aim of the study was to investigate the impact of information literacy on academic performance among undergraduate students in Nigeria.
 Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
 Findings: A study on the impact of information literacy on academic performance among undergraduate students in Nigeria found a significant positive correlation between information literacy skills and academic achievement. The research highlighted that students with higher levels of information literacy were more likely to demonstrate better performance in their coursework, exams, and overall academic outcomes.
 Unique Contribution to Theory, Practice and Policy: Social cognitive theory, information processing theory& constructivist learning theory may be used to anchor future studies on the impact of information literacy on academic performance among undergraduate students in Nigeria. Integrate information literacy instruction into the university curriculum across disciplines, ensuring that students acquire essential skills for locating, evaluating, and utilizing information effectively. Develop national guidelines for information literacy instruction within Nigerian higher education institutions, outlining standards and best practices for integrating information literacy into the curriculum.
