The Oakland–Alameda County Coliseum, or Oakland Coliseum for short, is a multi-purpose stadium in Oakland, California, United States, which is home to the Oakland Athletics of Major League Baseball (MLB). The stadium opened in 1966 and was the last remaining stadium in the United States shared by professional football and baseball teams having done so from 1968 until 2019. From 1966 until 1981 and again from 1995 until 2019, the stadium was home of the Oakland Raiders of the National Football League. It was also the home of the Oakland Invaders of the United States Football League from 1983 to 1985. The Coliseum was also home to some games of the San Jose Earthquakes of Major League Soccer in 2008–2009 and hosted games of the 2009 CONCACAF Gold Cup. The Oakland–Alameda County Coliseum complex consists of the stadium and the neighboring Oakland Arena.

The Coliseum has 6,300 club seats, 2,700 of which are available for Athletics games, 143 luxury suites, 125 of which are available for Athletics games, and a variable seating capacity of 46,867 (or 55,945 without tarps) for baseball and 63,132 for soccer. It has a seating capacity of 56,057 for football as of 2019. In seating capacity, Oakland Coliseum is the eighth-largest MLB stadium.

While an NFL venue, the stadium was the second-smallest NFL stadium, larger only than Dignity Health Sports Park, the temporary home of the Los Angeles Chargers.

On April 3, 2017, Opening Day, the Athletics dedicated the Coliseum's playing surface as Rickey Henderson Field in honor of MLB Hall of Famer and former Athletic Rickey Henderson.

The Polo Grounds was the name of three stadiums in Upper Manhattan, New York City, used mainly for professional baseball and American football from 1880 until 1963. As the name suggests, the original Polo Grounds, opened in 1876 and demolished in 1889, was built for the sport of polo. Bound on the south and north by 110th and 112th Streets and on the east and west by Fifth and Sixth (Lenox) Avenues, just north of Central Park, it was converted to a baseball stadium when leased by the New York Metropolitans in 1880. The third Polo Grounds, built in 1890 and renovated after a fire in 1911, is the one generally indicated when the Polo Grounds is referenced. It was located in Coogan's Hollow and was noted for its distinctive bathtub shape, very short distances to the left and right field walls, and an unusually deep center field.

In baseball, the original Polo Grounds was home to the New York Metropolitans from 1880 until 1885, and the New York Giants from 1883 until 1888. The Giants played in the second Polo Grounds for part of the 1889 season and all of the 1890 season, and at the third and fourth Polo Grounds from 1891 through 1957. The Polo Grounds was also the home field of the New York Yankees from 1913 until 1922 and the New York Mets in their first two seasons of 1962 and 1963. It hosted the 1934 and 1942 Major League Baseball All-Star Games.

In football, the third Polo Grounds was home to the New York Brickley Giants for one game in 1921 and the New York Giants from 1925 to 1955. The New York Jets of the American Football League played at the stadium from the league's inaugural season of 1960 through 1963.

Other sporting events held at the Polo Grounds included soccer, boxing, and Gaelic football. The last sporting event at the Polo Grounds was a football game between the New York Jets and the Buffalo Bills on December 14, 1963. Shea Stadium opened in 1964 and replaced the Polo Grounds as the home of the Mets and Jets. The Polo Grounds was demolished over a period of four months that year and a public housing complex, known as the Polo Grounds Towers, was built on the site.

The Tampa Bay Buccaneers are a professional American football team based in Tampa, Florida. The Buccaneers compete in the National Football League (NFL) as a member club of the league's National Football Conference (NFC) South division. The club joined the NFL in 1976 as an expansion team, along with the Seattle Seahawks, and played its first season in the American Football Conference (AFC) West division. Prior to the 1977 season, Tampa Bay switched conferences and divisions with Seattle, becoming a member of the NFC Central division. During the 2002 league realignment, the Buccaneers joined three former NFC West teams to form the NFC South. The club is owned by the Glazer family, and plays its home games at Raymond James Stadium in Tampa.

The Buccaneers were regarded as a perennial losing franchise for most of their first two decades of existence due to suffering 26 consecutive losses in their first two seasons (including a winless inaugural season) and 14 consecutive losing seasons from 1983 to 1996. Despite this lack of success, they are the first post-merger expansion team to win a division championship, win a playoff game, and host a conference championship game; a feat they accomplished by their fourth season in 1979. Aided by the Tampa 2 defensive scheme, the team improved their image during the late 90s, which culminated with their first Super Bowl title in Super Bowl XXXVII. Their 2002 championship remained their most recent playoff win for nearly two decades until they embarked on another run in 2020 that saw them reach Super Bowl LV.

Robert F. Kennedy Memorial Stadium, commonly known as RFK Stadium, was a historic multi-purpose venue located in Washington, D.C., along the Anacostia River. Opened on October 1, 1961, as District of Columbia Stadium, it was one of the first stadiums designed to accommodate both baseball and football, with a circular "cookie-cutter" layout. Built at a cost of $24 million, it initially seated around 43,500 for football and up to 45,000 for baseball. The stadium was renamed in 1969 to honor Senator Robert F. Kennedy following his assassination, reflecting its role as a national landmark.

Over its decades of operation, RFK hosted numerous professional and college teams. The Washington Redskins (now Commanders) called it home from 1961 to 1996, winning three Super Bowls during their tenure. In baseball, the Washington Senators played there from 1962 to 1971 before relocating to Texas, and the Washington Nationals used it temporarily from 2005 to 2007. Soccer was prominent too, with D.C. United of Major League Soccer residing from 1996 to 2017, alongside earlier teams like the Washington Whips (1967–1968), Washington Diplomats (1974–1981), and Team America (1983). College football teams included the George Washington Colonials (1961–1966) and Howard Bison (various years up to 2016). Other squads, such as the Washington Federals of the USFL (1983–1984) and Washington Freedom women's soccer (2001–2003), also played there.

The stadium hosted iconic events, including five NFC Championship games, two MLB All-Star Games (1962 and 1969), 1994 World Cup matches, 1996 Olympic soccer, and concerts by artists like the Beatles and the Grateful Dead.

RFK closed in 2019 after its final event. As of 2025, demolition is underway, with plans for a new stadium for the Washington Commanders set to open in 2030 on the site.

Soldier Field, located in Chicago, Illinois, is one of the most iconic stadiums in the United States. Originally opened in 1924, it was built as a memorial to U.S. soldiers who died in combat.

With a seating capacity of approximately 61,500, it is the smallest stadium in the NFL but remains a cherished venue due to its rich history and prime location near Lake Michigan.

Aside from sports, Soldier Field has hosted significant cultural and political events, including speeches by U.S. presidents and large-scale concerts featuring artists like Beyoncé and The Rolling Stones.

Located on the St. Johns River, it sits on 10 acres (4.0 ha) of land in downtown Jacksonville.

In addition to hosting the Jaguars, the stadium is also regularly used for college football, concerts, and other events.

Tiger Stadium, previously known as Navin Field and Briggs Stadium, was a baseball park located in the Corktown neighborhood of Detroit, Michigan. It hosted the Detroit Tigers of Major League Baseball from 1912 to 1999, as well as the Detroit Lions of the National Football League from 1938 to 1974. It was declared a State of Michigan Historic Site in 1975 and has been listed on the National Register of Historic Places since 1989. The stadium was nicknamed "The Corner" for its location on Michigan Avenue and Trumbull Avenue.

The last Detroit Tigers game at the stadium was held in September 1999. In the decade after the Tigers vacated the stadium, several rejected redevelopment and preservation efforts finally gave way to demolition. The stadium's demolition was completed on September 21, 2009, though the stadium's actual playing field remains at the corner where the stadium once stood. Since the spring of 2010, a volunteer group known as the Navin Field Grounds Crew (composed of Tiger Stadium fans, preservationists, and Corktown residents) has restored and maintained the field.

A plan to redevelop the old Tiger Stadium site would retain the historic playing field for youth sports and ring the 10-acre property with new development has received final approval, and funding.
