Many governments worldwide have been investing heavily in e-Government project as a strategy to provide the best governmental services to citizens. However, many governments and academic researchers recognized the problem of low-level of citizens' adoption toward e-Government services. Bahrain e-Government Authority is one of the governments that suffer from the lack of citizens' adoption of e-Government services, what caused serious problems to the authority. Therefore, this study is dedicated to address the factors that affect citizen's intention to adopt e-Government services from cultural, awareness and trust perspectives. Regression analysis is conducted to determine the relationship between culture, awareness and trust with adoption of e-Government. The results of the regression test showed strong evidence of a significant relationship between culture, awareness and trust and adoption of e-Government. However, the test indicated that trust had the highest level of relationship toward e-Government adoption. These results reveal that trust construct should be more considered by the e-Government authorities in Bahrain because it has a considerable impact on citizens' intention to use e-Government services. This will enable the authority to take actions to enhance citizens' trust, what will increase the rate of e-Government adopters.
