English: The Thap Po Sah Inu temple, also called the Po Sanu temple or Pho Hai Cham temple, is a Cham Hindu complex near the coastal town of Phu Hai in Binh Thuan province of Viet Nam. It is well connected by the coastal national highway. It is about 185 kilometers east of Ho Chi Minh, and 7 kilometers from Phan Thiết city.

The Po Sah Inu temple is from the 7th to 8th century, with some scholars suggesting 9th-century. It is dedicated to the Shiva tradition, with a Shiva linga in the main temple. The complex is ruined, but presently sporadically active and hosts goddess Po Sanu. Her name means "little goddess", and she is believed in the Cham tradition to be the daughter of Shiva and Po Nagar (Uma). The hilltop site and complex has three surviving Cham structures. It was much bigger and had more structures because at least seven structural platforms and ruins can be identified.

The temple complex sits on a jagati (platform), was built from bricks, has some Khmer influence. The style is closer in its inspiration to the beautiful temples of Po Nagar in Nha Trang.
