St George's Church, Portobello, was a Church of England church in the City of Sheffield, England. It is now part of the University of Sheffield and functions as a lecture theatre and student housing. St George's was the first of three commissioners' churches to be built in Sheffield under the Church Building Act 1818 (the other two being St Mary's Church, Bramall Lane and St Philip's Church, Netherthorpe). The church was designed by Woodhead and Hurst at a cost of £15,181 (equivalent to £1,120,000 in 2015), the whole cost being met by the Church Building Commission. It was built in the Perpendicular style, 122 feet (37 m) long and 67 feet (20 m) wide, and consisted of a flat-ceilinged nave with six bays, a single-bay chancel, and a 140 feet (43 m) high tower.
