The 21-year-old singer was scheduled to perform in Santo Domingo on September 13, but a government agency cancelled the concert, reported the New York Daily News.
The government commission, which oversees public performance, banned her performance because she "undertakes acts that go against morals and customs, which are punishable by Dominican law."
Cyrus' onstage antics include twerking, crotch-grabbing and sticking her tongue out.
The singer's camp has not commented so far.
