Valley Children's Stadium, also known as Jim Sweeney Field at Bulldog Stadium, is an outdoor college football stadium located on the campus of California State University, Fresno, in Fresno, California. It is the home field of the Fresno State Bulldogs, who play in the Pac-12 Conference.

Prior to the construction of Bulldog Stadium, Fresno State played at 13,000-seat Ratcliffe Stadium at Fresno City College, about five miles (8 km) southwest of campus. In the early 1970s, there were only two stadiums in the Fresno area, Ratcliffe and McLane, which made scheduling of local football games difficult. Those two stadiums had to host all local high school, community college and university games, which forced some high school games to be played on Thursday nights, rather than the traditional Friday nights.

The 1974 addition of Lamonica Stadium in Clovis eased the bottleneck somewhat, but efforts to build a stadium at Fresno State became serious in the mid-1970s. Bob Goss, chairman of the athletics booster organization the Bulldog Foundation, said in 1973: "I feel strongly the community of Fresno not only needs a new stadium, but can afford it, and is willing to get going as soon as possible on a drive to raise a part of the money."

In 1975, Fresno State students voted not to contribute to the stadium project via tuition fees, but the state budget included $1.2 million for it. A stadium steering committee was established in 1977, led by local businessman Leon Peters, looking to make the project a reality.

An initial round of construction bids came in over budget and the steering committee reworked their request. A second round of bidding offered better results and the local Robert F. Fisher Company was awarded the construction contract. Bulldog Stadium was completed in September 1980, a few months ahead of schedule, and had a seating capacity of 30,000.

It hosted the California Bowl from 1981 to 1991 and friendly soccer matches prior to the 1994 FIFA World Cup.

The completion of the stadium correlated with a drastic rise in the fortunes of the Fresno State football program, led by head coach Jim Sweeney, including multiple conference championships and finishing the 1985 season ranked 16th in the coaches' poll. But the program still had problems scheduling high-profile opponents, and a stadium expansion was proposed as a way to mitigate those issues, as well as boost recruiting efforts and revenue. The expansion, consisting of 22 "sky suites" added to the east side, as well as 2,000 more chair seats and 7,200 bench seats, was approved in 1989 and completed in 1991, increasing capacity from 30,000 to around 40,000.

Bulldog Stadium enjoys a reputation of having one of the premier home football environments among universities outside of the so-called "power conferences". Tailgate parties in the adjoining parking lots and athletic fields are an enormously popular pastime for Bulldog supporters and the fans are notable for their enthusiastic support within the stadium's environment. For several decades, supporters of Fresno State football have been nicknamed "The Red Wave" as a tribute to their swell of support and their tendency to be clad entirely in red clothing for home contests.
