Arulmigu Maha Muthu Mariamman Thevasthanam, Hindu temple in Kopisan Baru, Kampar District, Malaysia.

Arulmigu Maha Muthu Mariamman Thevasthanam is a Hindu temple in Kampar featuring traditional South Indian architectural style with carved deity figures and ornamental details adorning its surfaces. The complex includes spaces for worship, community gatherings, and religious learning activities.

The temple was built in 1962 as Kaliamman Kovil on 57,860 square feet of land donated by Gopeng Berhad. In 1964 renovations placed Goddess Mariamman as principal deity, led by Mr Suppaiyah with contractor Mr Arjunan. It was registered on 22 September 1967 as Sri Muthumariaman Kovil. After the land was gazetted in 2000 and reduced to 30,797 square feet, a new building was begun with a groundbreaking on 10 December 2006; the temple was renamed Arulmigu Maha Mariamman Thevasthanam on 4 May 2009 and consecrated on 12 December 2010.

The temple is dedicated to Goddess Mariamman, a deity revered by the local community for her protective power. Devotees gather here to perform prayers and maintain traditional Hindu observances throughout the year.

The temple stands in Kopisan Baru, Gopeng, in the Kampar District of Perak. Its land was reduced to 30,797 square feet when the site was gazetted in 2000, so the Kaliamman shrine and left hall were moved into the replacement building completed for the 2010 Kumbabishekam. Visitors should dress modestly and remove their shoes before entering.

During the 2010 consecration ceremony, a group of eagles circled above the temple, which participants viewed as a sign of divine presence. This unexpected natural event remains memorable to visitors and is often recounted as a special moment.
