The fracton topological orders are a new type of strongly correlated topological phases hosting fractional excitations which are immobile or mobile only in restricted sub-dimensional space. In this talk, I will introduce the quantum phase transition in the fracton topological orders. A fracton topological order has ground state degeneracy which scales up with the system size. The topological transition in our study is characterized by the breaking down of the ground state degeneracy. I will introduce how to develop a theory to study the phase transition in a class of fracton topological orders, and determine the critical points of the phase transition. Some universal results will be presented.
