All Saints Church, Ammanford is an Anglican parish church in the town of Ammanford, Carmarthenshire, Wales. It was erected between 1911 and 1915 by W. D. Jenkins of Llandeilo. The tower was added between 1924 and 1926 as a war memorial, this time the architect being Charles Mercer of Swansea. The church is located on the north side of Brynmawr Avenue, Ammanford, on College Street where it backs onto Church Street. The church was designated a Grade II-listed building on 8 October 1994, as "a powerfully designed example of a full-scale late Gothic Revival church on a prominent site".
