"Through their unwavering performance, professionalism and discipline, including during the Ebola epidemic, these brave women gained the respect of both the Government and the Liberian people," the Secretary General's spokesman said in a statement.
The 125 women and supporting personnel will return to India this weekend.
According to the statement, Ban commended the Formed Police Unit (FPU) for their contributions in creating an environment for Liberia to assume fully its security responsibilities by June 30, 2016, as mandated by the Security Council.
Ban underscored that the conduct of the FPU served as an example of how the deployment of more female uniformed personnel can help the United Nations in its efforts to combat sexual exploitation and abuse.
The Secretary-General thanked all the women who served in the FPU for inspiring all Liberians, as well as current and future generations of female police officers, and becoming role models for gender equality.
He also payed tribute to the outstanding contribution of the Indian government in support of the United Nations peace operations.
