What is the nature of the data?  Is it reasonable to assume that the distribution shape is the same in both (or all) groups?  To see why I ask that question, see the "Do non-parametric tests compare medians?" section in Chapter 10 of "Statistics at Square One".

Hello All,

What is the right statistical test to determine whether the median of multiple
groups are statistically significant or not?
