Cardiff Reform Synagogue (Welsh: Synagog Ddiwygiedig Caerdydd; formerly Cardiff New Synagogue; Welsh: Synagog Newydd Caerdydd)[1] is a Reform Jewish synagogue, located on Moira Terrace, Adamsdown, in Cardiff, Wales, in the United Kingdom.

This attracted newly arrived immigrants from Germany, Czechoslovakia, Austria and elsewhere.

[3] Services were initially held in Cardiff's Temple of Peace and Health, a non-religious civic building in Cathays Park.

[3] In 2010, the synagogue was awarded over £33,000 by the Heritage Lottery Fund for a project showing how Reform Jews, some of whom had fled from central Europe, had adapted to life in Wales.

[4] In 1952, the community purchased Salem Welsh Baptist Chapel in Moira Terrace, Adamsdown, Cardiff, which it converted for use of a synagogue.
