The aim of this research is to examine the effect of organisational culture on organisational performance in the context of the hospitality industry in the UK. Organisational culture was studied based on the Denison model. The study was conducted based on a quantitative research method and primary data was collected, with questionnaires, from 440 employees in the hospitality industry. The study reveals that organisational culture significantly affects organisational performance. Moreover, it is found that adaptability and mission are two key elements of organisational culture that significantly affect organisational performance. Furthermore, intrapreneurship fully mediates the relationship between adaptability and organisational performance. In addition, intrapreneurship fully mediates the relationship between mission and organisational performance. Hence, managers working in the hospitality industry are required to give considerable attention to adaptability and mission as two important elements of organisational culture in order to achieve intrapreneurship, and to ultimately improve the performance of an organisation.
