St. Peter's Church, Aungier Street, Dublin, Church building in Aungier Street, Dublin, Ireland

St. Peter's Church was a Church of Ireland parish church on Aungier Street, built in 1685 on former Whitefriars land. It was largely rebuilt in Georgian style by architect Michael Wills from 1750 to 1752, enlarged in 1773, and rebuilt in Gothic style by Edward Henry Carson in 1867, keeping only the nave walls. The church was demolished in 1983; the Dublin YMCA building now stands on the site.

The church was built on former Whitefriars land and dates from 1685. Over the centuries, major transformations reshaped the building to fit changing styles and community needs.

The churchyard served as a burial ground for parishioners and for Dublin's Huguenot community until about 1883. Among those interred were the Earl of Roden and his family, several bishops, the judge Charles Burton, Mary Anne Holmes and Black Jack Fitzgibbon, Earl of Clare. When the land was developed in the 1980s, the Huguenot remains were moved to Mount Jerome cemetery.

The church was demolished in 1983, and the Dublin YMCA hostel, granted planning permission in December 2000, now occupies the Aungier Street site. Nothing of the church itself remains to visit; the war memorial was moved to St. Catherine and James Church on Donore Avenue in 2015.

Arthur Wellesley, who would become the Duke of Wellington, received his baptism here in 1769. This event connected one of Britain's most influential military leaders to this now-vanished religious site in Dublin.
