The State Sangha committee is asking him to leave Sadhu Buddhist Monastery in Rangoon, saying the speech he gave in September at a branch of Aung San Suu Kyi's National League of Democracy in Mandalay, in central Burma, was inappropriate.
Ashin Pyinyar Thiha told the French news agency he will appeal the decision.
In recent months the Sadhu monastery has held a series of political events.
Burma's new government took over in March and has shown tentative steps toward democratic reform.
Last month, U.S. Secretary of State Hillary Clinton made a landmark visit to the Southeast Asian country to assess the progress of its reforms.
