First Church of Christ, Scientist, Perth, Art Deco heritage church in St Georges Terrace, Perth, Australia.

First Church of Christ, Scientist, Perth stands at 264 St Georges Terrace, on the corner of Elder Street. The 1939 church was built after a temporary auditorium went up on the site in 1933, on land bought in 1926 that included outbuildings of the old Pensioner Barracks.

Christian Science reached Perth in 1904, when adherents arriving from Sydney began weekly meetings to read Bible lessons; the first public service followed in 1908. The group formed the Christian Science Society by 1912 and became First Church of Christ, Scientist, Perth in 1920, meeting in rented rooms. In 1926 the church bought the St Georges Terrace and Elder Street site, which held outbuildings of the old Pensioner Barracks; an auditorium served from 1933 until the church was built in 1939.

The congregation began in 1904 when adherents arrived from Sydney and met weekly to read Bible lessons; the first public service followed in 1908, and the society became First Church of Christ, Scientist, Perth in 1920. Services were long held in rented rooms across the city before the St Georges Terrace church opened.

The church stands at 264 St Georges Terrace, on the corner of Elder Street, in Perth's central business district. The site was bought in 1926 and had earlier held outbuildings of the Pensioner Barracks. The auditorium of 1933 served as a temporary church until the 1939 building was ready.

The site bought in 1926 included outbuildings of the original Pensioner Barracks; the church itself was preceded by a temporary auditorium built in 1933, six years before the 1939 church. The original harmonium gave way to a pipe organ in 1953, upgraded in 1983.
