We show that extremal Kerr-Bolt spacetimes have a hidden con- formal symmetry. In this regard, we consider the wave equation of a massless scalar field propagating in extremal Kerr-Bolt spacetimes and find in the ”near region”, the wave equation in extremal limit can be written in terms of the SL(2,R) quadratic Casimir. Moreover, we obtain the microscopic entropy of the extremal Kerr- Bolt spacetimes also we calculate the correlation function of a near- region scalar field and find perfect agreement with the dual 2D CFT.
