Moriah Aman, Cwmaman was a Welsh Independent (Congregationalist) chapel in Fforchaman Road, Cwmaman, Rhondda Cynon Taf, Wales.

The cause at Moriah Aman was established in 1853 on the initiative of the Rev. John Davies, minister of Saron, Aberaman. It was originally a Sunday School with prayer meetings being held later in local houses. The first chapel was opened on 2 October 1855 with 27 members being transferred from the mother church at Saron.

A new chapel opened in 1893 had searing for 650 people with the gallery accommodating 250. Membership was 435 in 1905.

In 1908, the members of Moriah Aman supported the actions of the church at Bethlehem, Abercwmboi in expelling members who supported the New Theology ideas of R.J. Campbell.

Moriah Aman eventually closed in 1988. In 1995 the building was refurbished as a Pentecostal church.
