The paper examined the influence of corporate culture on public relations practice in Nigeria. Public relations practitioners might have seen corporate culture in relation to the practice of public relations as a natural phenomenon but scholars have hardly paid research attention to it as an important aspect of public relations practice. Scholars are curious to know what influence corporate culture might have on the communication process and relationship building between organizations and their stakeholders. Recent studies tend to link corporate culture with corporate change which is further seen as critical to the success of organisation. The theoretical framework for this study consists of organizational culture theory. It was established that perception of corporate culture has a direct bearing with corporate relationship.
