Valley Parade, currently known as University of Bradford Stadium for sponsorship reasons, is an all-seater football stadium in Bradford, West Yorkshire, England. The stadium was built in 1886 as the home of Manningham Rugby Football Club; it remained so until 1903, when the club changed code from rugby league to association football, and became Bradford City A.F.C.. Valley Parade has since been Bradford City's home ground, and is now owned by the pension fund of the club's former chairman Gordon Gibb. The stadium has also hosted Bradford (Park Avenue) for one season and the rugby-league side Bradford Bulls for two seasons, and has accommodated a number of England youth team fixtures. In 1908, the football architect Archibald Leitch was commissioned to redevelop the ground when Bradford City were promoted to the First Division.

Few changes were made until a fatal fire on 11 May 1985, when 56 supporters were killed and at least 265 were injured. The stand had been officially condemned and was due to be replaced with a steel structure after the season ended. Oliver Popplewell published his inquiry into the fire, which led to the introduction of new safety legislation for sports grounds across England. Following the fire, the stadium underwent a £2.6-million redevelopment and was re-opened in December 1986.

The ground underwent significant changes in the 1990s and the early 2000s, and now has a capacity of 25,136. The attendance record of 39,146 was set in 1911 at an FA Cup tie against Burnley, making it the oldest-surviving attendance record at a Football League ground in England. The highest attendance at Valley Parade, as it is now, is 24,343, was set at a pre-season friendly against Liverpool in 2019. In 2022, the stadium's name was changed because of sponsorship from the University of Bradford.

Manningham Rugby Football Club,which was formed in 1876, played games at Cardigan Fields in the Carlisle Road area of Bradford. When their ground was sold to facilitate the construction of Drummond School, the club bought one-third of the Valley Parade site in Manningham, taking a short-term lease on the rest of the land in time to play there for the 1886–1887 season. The new ground and the road upon which it was built adopted the area's name Valley Parade, which was derived from the steep hillside below Manningham. The land was previously a quarry, and formed part of a larger site that was owned by Midland Railway Company.

The club spent £1,400 appointing designers to oversee the excavation and levelling of the land, and moved a one-year-old stand from Carlisle Road to the highest part of the new ground. The original ground comprised the relocated stand, a 2,000-capacity stepped enclosure with the players' changing rooms beneath the stand, the playing area, a cinder athletics track and fencing to limit the capacity to 18,000. The playing field was made of ballast, ashes, soil and sods. The ground was officially opened on 27 September 1886 for a game against Wakefield Trinity, which was watched by a capacity crowd, but construction work meant most of Manningham's early games were away fixtures.

On 25 December 1888, 12-year old Thomas Coyle was killed at the ground when the barrier under which he was sitting collapsed on him, breaking his neck. An inquest decided the death was an accident that happened due to the weight of spectators leaning on the barrier. The takings from the game, totalling £115, were distributed to Coyle's family and those of other boys who were injured in the incident.

Manningham RFC continued playing until 1903, when financial difficulties caused by relegation at the turn of the 20th century prompted club officials to change codes from rugby league to association football. The first association-football game to be played at Valley Parade on 6 April 1903 was a promotional fixture between a side of West-Yorkshire footballers and Sheffield United's 1903 FA Cup-winning side. The game was organised to stimulate interest in the sport in Bradford and attracted 8,000 fans. The new football club, Bradford City, were elected to The Football League's Division Two the following month. Bradford City's first game at Valley Parade came on 5 September 1903 against Gainsborough Trinity, drawing a crowd of 11,000. As a result of alterations first implemented in 1897, City players originally changed in a shed behind one end of the ground and visiting teams used the old rugby club's dressing rooms at the back of the nearby Belle Vue Hotel. After City's 5–1 defeat by Manchester United on 10 February 1906, United player Bob Bonthron was attacked as he left the ground. As a result, The Football Association (FA) closed the ground for 14 days, ordering City to switch its changing rooms to the nearby Artillery Barracks for the 1906–07 season. Several supporters faced criminal proceedings for the incident.

After Bradford City won the Division Two championship in 1907–08, the club hurriedly reconstructed the ground to prepare for the club's first season in Division One. Football architect Archibald Leitch was commissioned to design new terracing in the paddock—a standing area in front of the 5,300-seat main stand that was built in 1908—and build a Spion Kop at the north side of the ground and an 8,000-capacity stand at the Midland Road end opposite the main stand. Further work was done to lower the railings, erect barriers, move the pitch and add extra turnstiles. The changing rooms were moved and a tunnel leading from the rooms underneath the Kop along the main-stand side of the ground was built. The total project cost £9,958, and raised the capacity to 40,000. The work was completed midway through the 1908–09 season. Following the work, the first match took place on 25 December 1908, when 36,000 fans saw Bradford City host Bristol City. The improvements allowed Bradford City to set their attendance record of 39,146 on 11 March 1911 against Burnley during the club's FA-Cup-winning run. It is the longest-surviving attendance record at any league ground in England.
