St. George's Church is a former parish church in Dublin.Designed by Francis Johnston, it is considered to be one of his finest works. It is located at Hardwicke Place, just north of the city centre.

The elegant spire, 200 feet (61.0 m) high, became a landmark of the north inner city.

Twenty-two years after the church was built problems developed when the wide roof began to splay further than it should, due to the strain of the wide-span timber trusses. Civil engineer Robert Mallet, whose father ran an iron foundry in Dublin, created cast-iron trusses to haul the church back into shape.

In the 1980s scaffolding had to be erected around the spire because the Portland stone was cracking due to expansion of the iron cramps that held it in place. The Church of Ireland, having tried in vain to raise funds for the restoration of the church, sold the building in 1991 to an actor, Mr Sean Simon, who had plans to turn it into a theatre.

After its deconsecration, the bells (which Leopold Bloom heard ringing in Ulysses) were removed to Taney Parish church in Dundrum, while the ornate pulpit was carved up to decorate Thomas Read's pub in Parliament Street.

The church in Temple Street then became the Temple Theatre, then a night-club, but further attempts were made to raise public funds for its restoration; first, in 1991, to celebrate Dublin's role as European City of Culture, and later from the Millennium Committee.

In 2004 the building found a new purchaser who oversaw extensive restoration and renovation to provide office facilities.
