The study investigated product creativity and organisational competitiveness in Nigerian private organisations with a view to ascertaining the extent to which product creativity (product line, differentiation, imitation, and innovation) influences creativity and the extent to which product creativity enhances organisational competitiveness. The study employed crosssectional survey design, and simple random sampling served to select respondents from ten multinational companies across the six geopolitical zones in Nigeria. The study employed constructs consistent with those from empirical studies and used a five-point Likert scale for all the measures. The data were analysed using structural equation modelling. Results show that three out of the four constructs of creativity are significant predictors of organisational competitiveness. Thus, product line (combination), product differentiation, and product innovation significantly influence creativity, and creativity predicts organisational competitiveness. Business managers can thus enhance the competitiveness of their products through product line, differentiation, and product innovation. However, the framework of the study is not exhaustive. Future studies should attempt a framework that will integrate additional creativity constructs.
