All Saints Church is the Anglican parish church of Roffey, in the Horsham district of the English county of West Sussex. The present church, built to serve the Victorian suburb of Roffey—part of the ancient market town of Horsham—replaced a schoolroom in which religious services had been held since 1856. Arthur Blomfield's Early English-style church, built of locally quarried sandstone and funded by a widow as a memorial to her late husband, was completed in 1878 and was allocated a parish immediately. Roman Catholic services were also held in the building to serve Roffey's Catholic population, but these ceased in the early 21st century. English Heritage has listed the church at Grade II for its architectural and historical importance.
