All Saints Church, Grangegorman, Church of Ireland building in Grangegorman, Dublin, Ireland

All Saints Church is a freestanding Church of Ireland building in Grangegorman with a four-bay nave and a two-bay chancel to the east. The structure features octagonal turrets on the south side and displays red brick walls with black decorative courses, along with original stained glass windows and pointed arch openings.

All Saints was built in 1828 to designs by John Semple and became a parish in 1829, carved out of parts of St. Michan's, St. Paul's and St. George's. Thomas Drew remodelled it along Tractarian lines, redesigning the chancel in 1856 and adding the baptistery in 1889. A fire in 1966 destroyed notable features, including the 19th-century roof.

The church reflects liturgical ideas from the 19th century that shaped the Church of Ireland, emphasizing formal worship practices. Visitors can see this in the careful interior design that keeps these traditions alive today.

The building is viewable from outside and located in a residential neighborhood in Dublin that is easy to reach. The church holds regular services and is now managed as part of a larger parish group.

The church's organ was built by Telford and Telford in the late 19th century and first stood in St Philip's Church, Milltown; it moved to the Church of St Mary in Mary Street before arriving here in 1986. The choir traces its origins to the parish's earliest days, when adult singers volunteered but the children were paid; in the 1940s the children went on strike for higher salaries.
