In this paper, we extend the concept of partial correlation coefficient of real random variables to fuzzy random variables. In fact, our objective here is to propose a method of partial correlation analysis based on the definition of simple correlation coefficient between fuzzy random variables. The analysis of partial correlation is developed here to show the relation between fuzzy random variables while controlling for a third or more other fuzzy random variables. Some properties of this definition and an example has been presented to complete our discussion on the partial correlation coefficient between fuzzy random variables.
