Bethania is an Independent chapel in Phillip Street, Mountain Ash, Glamorgan, Wales.

The church began in the form of a Sunday school built in 1850, although earlier meetings had been held at the home of one Daniel Rowlands, which later became the Glancynon Inn.

[1] This coincided with the sinking of the Deep Duffryn Colliery in 1855, which led to a large influx of people into the area.

[1] Coleman kept a grocery and drapery business at 54 Commercial Street, Mountain Ash.

Mountain Ash and District Choral Society hold their practices and rehearsals at the vestry.
