In this article, we examine the relationship between ethical organisational culture and organisational innovativeness. A quantitative empirical analysis is based on a survey of a total of 719 respondents from all levels of three Finnish organisations, both general staff and managers. The organisations belong to both the private and public sectors. The results of this study show that organisations’ ethical culture is associated with their organisational innovativeness, and that different dimensions of ethical culture are associated with different dimensions of organisational innovativeness. The ethical culture of the organisation had a specific role in process and behavioural innovativeness. It was found that congruency of management was the single dimension with the highest effect on organisational innovativeness overall and specifically on process and behavioural innovativeness. These findings suggest that when organisations are aiming for specific outcomes, such as organisational innovativeness, they need to be aware of what dimensions of ethical culture are particularly relevant.
