Five specific objectives of the study were conceptualized and a concomitant five research questions and hypotheses were stated. The theory that underpins this study is the Principal/Agent theory. The sample size for this study is one hundred and thirty two (400) respondents. The population of the study is 5825. The sample size was obtained using the Slovin formular of Sample determination (1960). Data for this study was obtained using the structured questionnaires as well as personal interview with respondents. The triangulation of the quantitative and qualitative analysis was carried out. The collected data was analyzed using the statistical package for social sciences version 20 (SPSS version 20). The reliability of the research instrument was determined by the benchmark of a Cronbach Alfa of 0.70 and above. The null hypotheses were tested using the statistical package for social sciences (Version 20). The analysis indicated that the dimensions of criterion-variable (corruption) positively correlated with the measures of the predictor variable (service delivery). The study therefore concluded that corruption impacted on service delivery in Imo State Civil Service. It is recommended that corruption and its dimensions should be mitigated in Imo State Civil Service in order to enhance service delivery to the residents of Imo State.
