Pro-social behaviour among Nigerian Police personnel is influenced by many factors some of which have been researched upon in the past. This paper, therefore, investigates some psychological determinants of pro-social behaviour among early career police personnel in the Ibadan metropolis, Nigeria. The study adopted the descriptive survey design of correlational type. The sample comprised 246 Nigerian Police personnel in the Ibadan metropolis, Nigeria. Data collected were analysed using simple percentage, Pearson Product Moment Correlation (PPMC) and multiple regression statistics at 0.05 margin of error. Findings revealed that emotional intelligence (r-140; p<0.05), career efficacy (r-342; p<0.05), career resilience (r-071; p<0.05); and career optimism (r-25; p<0.05) had significant relationship with pro-social behaviour among early career police personnel in the Ibadan metropolis, Nigeria. There were also significant correlations among the independent variables (emotional intelligence, career efficacy, career resilience and career optimism) on the dependent variable (pro-social behaviour) among early career police personnel. In terms of magnitude of contribution, career efficacy made the most significant contribution (B= 313; t-5.700: p<0.05) followed by career optimism (3= 223; -4.087 P<0.05), emotional intelligence (B-094; t-1.723; p<0.05) and career resilience (- 049, t-906: p<0.05). The implications of these findings are discussed in the study. These findings are discussed with a view to enhancing pro-social behaviour of police personnel in Nigeria.
