Holy Trinity Church, Fortitude Valley, Anglican church in Fortitude Valley, Australia.

Holy Trinity Church is a brick and stone Anglican church at 141 Brookes Street, Fortitude Valley, built 1876–77 to a design by Francis Drummond Greville Stanley. It has a clerestoried nave flanked by aisles and crossed by transepts, on a stone base of dark brick laid in English bond, with window surrounds, string courses and copings in cement render. The chancel and sanctuary were added in 1921.

Construction began in 1876 under architect Francis Drummond Greville Stanley to replace an earlier structure that could no longer serve the expanding congregation. The new design reflected contemporary Gothic Revival preferences popular in church building during that era.

The parish began in 1856 with the Rev. E. K. Yeatman, and its boundaries once took in Sandgate, New Farm, Enoggera and Bowen Hills. The precinct pairs the 1877 church with a hall by diocesan architect John Hingeston Buckeridge and an 1891 rectory by F. D. G. Stanley.

The church stands on a site bounded by Church, Wickham and Brookes Streets in Fortitude Valley, with the parish hall and rectory sharing the grounds. It is an active Anglican parish church, so visits are best arranged outside service times. The 1956 brick retaining wall in the grounds commemorates parishioners who died in World War II.

The 1929 reredos behind the altar was designed by Lange Leopold Powell of Atkinson, Powell and Conrad and carved by Andrew Lang Petrie. A brick retaining wall added in 1956 commemorates parishioners who died in World War II. The 1925 clerestory windows replaced earlier ones a donor called an ugly blot.
