This study examined the Financing of projects by Community Based Organizations in Cross River State, Nigeria. One statement of the hypothesis was formulated to guide the study. The literature review was carried out based on the variable under study. The survey research design was considered most suitable for the study. A stratified random sampling technique was adopted in selecting the sample for the study. The Educational Activities of Community-Based Organizations and Sustainable Development Questionnaire (EACBOSDPQ) was the instrument used for data collection. The reliability estimate of the instrument was 0.81 using the Cronbach Alpha method. To test the hypothesis formulated for the study, Pearson’s Product Moment Correlation statistical tool was used. The hypothesis was tested at a 0.05 level of significance. The findings from the study showed that there is a significant relationship between parent-teacher organizations and the implementation of sustainable development. Also, neighborhood associations do not significantly relate to the implementation of sustainable development. It was recommended among others that CBOs should be empowered educationally and financially so that they can help in the financing of community projects.
