This paper presents an investigation of the moderation effect of the Saudi culture referred to as Wastta on the adoption of e-government in Saudi Arabia from the perspective of citizens. A hierarchical multiple regression analysis is conducted on the data collected through the survey of Saudi citizens. The study shows that Wastta influences the adoption of e-government through its moderating effect on the perceived ease of use and the perceived usefulness of e-government. This study contributes to the e-government research by highlighting the moderation effect of Wastta on e-government adoption in a developing country context.
