Patcham is a suburb in the city of Brighton and Hove, in the ceremonial county of East Sussex, England. It is about 3 miles (5 km) north of the city centre. It is bounded by the A27 to the north, Hollingbury to the east and southeast, Withdean to the south and the Brighton Main Line to the west. The A23 passes through the area.

All Saints Church is the Anglican parish church of Patcham, an ancient Sussex village which is now part of the English city of Brighton and Hove. A place of worship has existed on the hilltop site for about 1,000 years, but the present building has Norman internal features and a 13th-century exterior. Several rounds of restoration in the Victorian era included some structural additions. A wide range of monuments and wall paintings survive inside, including one commemorating Richard Shelley—owner of nearby Patcham Place and one of the most important noblemen in the early history of Brighton. The church, which is Grade II* listed, continues to serve as the Anglican place of worship for residents of Patcham, which 20th-century residential development has transformed from a vast rural parish into a large outer suburb of Brighton.
