The study looked into the connection between street hawking and girl child's academic performance in Calabar Municipal Local Government Area, Cross River State, Nigeria. The study primarily investigated the association between street hawking and a girl child academic performance through her school attendance issue and the association between street hawking and her academic performance as a result of her lateness to school. Cognitive child development theory served as the theoretical underpinning for the investigation. 200 respondents were chosen using a simple random sampling technique via the balloting process. A 20-item survey titled "street hawking and academic performance of girl child (SHAPOGC)" was used to gather data. For statistical analysis, the chi-square was employed, with a degree of freedom of 1. According to the study's findings, street hawking has a detrimental impact on girls' academic performance. And a significance level of 0.05 were applied to the testing of two hypotheses.The findings demonstrated a substantial correlation between street hawking and a girl child's academic performance as measured by her attendance at school, as well as a significant association between street hawking and a girl child's academic performance as a result of arriving late to school. Based on the findings, it was suggested that the government enact and enforce laws prohibiting child hawking during school hours, that religious and traditional leaders, non-governmental organizations, and educators educate and raise awareness among parents about the risks of enlisting their children in child labor through street hawking, and that the government work with school principals to address the issues of late arrivals, poor academic performance, and non-attendance among girls in order to improve their academic performance.
