Huntington Bank Field is a stadium in Cleveland, Ohio. It is the home field of the Cleveland Browns of the National Football League (NFL), and serves as a venue for other events such as college and high school football, soccer, hockey, and concerts. It opened in 1999 as Cleveland Browns Stadium and was known as FirstEnergy Stadium from 2013 to 2023 before briefly reverting to its original name until 2024. The initial seating capacity was listed at 73,200 people, but following the first phase of a two-year renovation project in 2014, was reduced to the current capacity of 67,431. The stadium sits on 31 acres (13 ha) of land between Lake Erie and the Cleveland Memorial Shoreway in the North Coast Harbor area of downtown Cleveland, adjacent to the Great Lakes Science Center and Rock and Roll Hall of Fame. Cleveland Stadium stood on the site from 1931 to 1996.

Huntington Bank Field is located on the site of Cleveland Stadium, commonly called Cleveland Municipal Stadium, a multipurpose facility built in 1931 that served as the Browns' home field from their inception in 1946 through the 1995 season. During the 1995 season, owner Art Modell announced his plans to move the team to Baltimore, which resulted in legal action from the city of Cleveland and Browns season ticket holders. The day after the announcement was made, voters in Cuyahoga County approved an extension of the original 1990 sin tax on alcohol and tobacco products to fund renovations to Cleveland Stadium. Eventually, as part of the agreement between Modell, the city of Cleveland, and the NFL, the city agreed to tear down Cleveland Stadium and build a new stadium on the same site using the sin tax funds. Modell agreed to leave the Browns name, colors, and history in Cleveland and create a new identity for his franchise, eventually becoming the Baltimore Ravens, while the NFL agreed to reactivate the Browns by 1999 through expansion or relocation of another team. Demolition on the old stadium began in November 1996 and was completed in early 1997. Debris from the former stadium was submerged in Lake Erie and now serves as an artificial reef.

Ground was broken for the new stadium on May 15, 1997, and it opened in July 1999. The first event was a preseason game between the Browns and the Minnesota Vikings on August 21, followed the next week by a preseason game against the Chicago Bears. The first regular-season Browns game at the stadium was played the evening of September 12, 1999, a 43–0 loss to the Pittsburgh Steelers.

In 2011, local comedian and Browns fan Mike Polk referred to the stadium as the "factory of sadness" in a video recorded outside the stadium in which he complains about the team's futility. In 2021, after the Browns defeated the Steelers at Acrisure Stadium, local TV station WKYC broadcast a segment with Polk where he "closed" the "factory of sadness".

Through the 2023 season, Huntington Bank Field is the only NFL venue that has yet to host a postseason game of any kind. The Browns are one of five teams who have yet to host a home playoff game in their current stadium, along with the Atlanta Falcons, Las Vegas Raiders, Los Angeles Chargers, and New York Jets. Those facilities, however, have each hosted the Super Bowl, while the Jets' home, MetLife Stadium, and the Chargers' home, SoFi Stadium, have also hosted home playoff games for their other tenants, the New York Giants and Los Angeles Rams, respectively.

The Browns lease at the stadium is set to expire at the end of the 2028 season. Cleveland Mayor Justin Bibb and the Browns announced in October 2024 that the team plans to construct a new indoor stadium in suburban Brook Park, at a site adjacent to Cleveland Hopkins International Airport, in time for the 2029 season. The current naming rights deal specifies that the Huntington Bank Field name will be transferred to the new facility once it opens. The city of Cleveland objected to the project, saying such a move would violate Ohio's Modell Law, which is designed to prevent franchises from leaving publicly funded facilities. In response, the team sued the city in October 2024 for clarification on the Modell Law, and the city countersued in January 2025 to enforce the Modell Law. Dennis Kucinich, who served as mayor of Cleveland in the late 1970s and was one of the main authors of the Modell Law when he served in the Ohio Senate, filed a lawsuit in late August 2025 against the Browns on behalf of taxpayers for enforcement of the Modell Law.

Public funding for the stadium was approved by the Ohio legislature on June 30, 2025, and the Ohio Department of Transportation approved the construction permit for the stadium on September 18, 2025, after it was found that it would not interfere with the airport. The Browns and the city of Cleveland announced an agreement on October 13, 2025, that calls for the team to pay the city $100 million, including the costs for demolition of the current stadium, and the Browns will have options to extend the lease through the 2029 and 2030 seasons if the new stadium is not completed in time. The city agreed to drop all lawsuits related to the move and cooperate with the new stadium development including infrastructure improvements around the airport.

The stadium was designed by Populous, which was known at the time as the Sport Venue Event Division of Hellmuth, Obata & Kassabaum (HOK). Indianapolis-based Huber, Hunt & Nichols was the construction manager. The stadium is a concrete and glass structure, using precast concrete and cast in-place for the upper concourse. Natural stone accents were used at the base of the stadium. The construction of the concrete superstructure took more than 6,000 truckloads of concrete, or the equivalent of 60,000 cubic yards (46,000 m³), with a weight of approximately 235 million pounds (107,000,000 kg).
