Thích Thiên-Ân (釋天恩) (September 22, 1925—November 23, 1980) was an American teacher and Buddhist monk of Vietnamese Thiền (Zen) Buddhism and was active in the United States from 1966 to 1980.

A few years later, his enthusiastic students encouraged Thích Thiên-Ân to apply for permanent residence and open a meditation center that included a place for practitioners to live and study Zen Buddhism.

In 1970, he founded the International Buddhist Meditation Center in the Koreatown section of Los Angeles, California .

In addition, he taught Eastern Philosophy and Asian Studies at Los Angeles City College.

He continued teaching at his center until he died in 1980 at the age of 54, succumbing to the effects of the liver cancer.
