Downtown Pittsburgh, colloquially referred to as the Golden Triangle, and officially the Central Business District, is the urban downtown center of Pittsburgh, Pennsylvania, United States. It is located at the confluence of the Allegheny River and the Monongahela River whose joining forms the Ohio River. The triangle is bounded by the two rivers.

The area features offices for major corporations such as PNC Bank, U.S. Steel, PPG, Bank of New York Mellon, Heinz, Federated Investors, and Alcoa. It is where the fortunes of such industrial barons as Andrew Carnegie, Henry Clay Frick, Henry J. Heinz, Andrew Mellon and George Westinghouse were made. It contains the site where the French fort, Fort Duquesne, once stood.

The Central Business District is bounded by the Monongahela River to the south, the Allegheny River to the north, and I-579 (Crosstown Boulevard) to the east. An expanded definition of Downtown may include the adjacent neighborhoods of Uptown/The Bluff, the Strip District, the North Shore, and the South Shore.

Downtown is served by the Port Authority's light rail subway system (known locally as the "T"), an extensive bus network, and two inclines (Duquesne Incline and Monongahela Incline). The Downtown portion of the subway has the following stations:

T Stations

• Station Square on the South Shore in the Station Square development (street-level station)
• First Avenue near First Avenue & Ross Street, Downtown (elevated station)
• Steel Plaza at Sixth Avenue & Grant Street, Downtown (underground station)
• Penn Plaza near Liberty Avenue & Grant Street, Downtown (underground, limited service)
• Wood Street at the triangular intersection of Wood Street, Sixth Avenue, and Liberty Avenue, Downtown (underground station)
• Gateway Center at Liberty Avenue & Stanwix Street, Downtown (underground station)
• North Side near General Robinson Street & Tony Dorsett Drive on the North Shore (underground station)
• Allegheny near Allegheny Avenue & Reedsdale Street on the North Shore (elevated station)

Downtown is also home to the Pittsburgh Amtrak train station connecting Pittsburgh with New York City, Philadelphia, and Washington, D.C. to the east and Cleveland and Chicago to the west. Greyhound's Pittsburgh bus terminal is located across Liberty Avenue from the Amtrak Station, in the Grant Street Transportation Center building.

Major roadways serving Downtown from the suburbs include the "Parkway East" (I-376) from Monroeville, the "Parkway West" (I-376) from the airport area, and the "Parkway North" (I-279) from the North Hills, and (I-579) in Downtown Pittsburgh. Other important roadways are Pennsylvania Route 28, Pennsylvania Route 51, Pennsylvania Route 65, and U.S. Route 19.

Three major entrances to the city are via tunnels: the Fort Pitt Tunnel and Squirrel Hill Tunnel on I-376 and the Liberty Tunnels. The New York Times once called Pittsburgh "the only city with an entrance," specifically referring to the view of Downtown that explodes upon drivers immediately upon exiting the Fort Pitt Tunnel. Also traveling I-279 south and I-376, the city "explodes into view" when coming around a turn in the highway.

Downtown surface streets are based on two distinct grid systems that parallel the Allegheny and Monongahela rivers. These two grids intersect along Liberty Avenue, creating many unusual street intersections. Furthermore, the Allegheny grid contains numbered streets, while the Monongahela grid contains numbered avenues. And, in fact, there are cases where these numbered roadways intersect, creating some confusion (i.e. the intersection of Liberty Avenue and 7th Street/6th Avenue). This unusual grid pattern leads to Pittsburghers giving directions in the terms of landmarks, rather than turn-by-turn directions.

Pittsburgh is nicknamed "The City of Bridges". In Downtown, there are 10 bridges (listed below) connecting to points north and south. The expanded definition of Downtown (including the aforementioned surrounding neighborhoods) includes 18 bridges. Citywide there are 446 bridges. In Allegheny County the number exceeds 2,200.

Downtown contains a wealth of historic, cultural, and entertainment sites. While most people still consider the entire Downtown as one neighborhood, there are several significant subdistricts within the Golden Triangle.

• The Pittsburgh Central Downtown Historic District is a historic district in the central business district. It is bounded by Wood Street, Forbes Avenue, Grant Street, and Liberty Avenue. It was listed on the National Register of Historic Places (NRHP) on December 17, 1985.
• Point State Park area: At the triangle's tip is Point State Park with its giant fountain and the Fort Pitt Museum. This park was the original site of both Fort Duquesne by the French and the subsequent Fort Pitt by the British.
• The Cultural District along Penn and Liberty avenues on the Allegheny River includes numerous theaters, galleries, and concert halls including Heinz Hall, Byham Theater, O'Reilly Theater, Benedum Center, and Wood Street Galleries as well as restaurants and housing. The Penn-Liberty Historic District encompasses the Penn & Liberty avenue corridor in the Cultural District.
• The Fifth & Forbes Corridor is Downtown's shopping district along Fifth and Forbes avenues and includes historic Market Square. Downtown is home to numerous independent retailers plus large retailers such as Burlington Coat Factory and Brooks Brothers.
• The Grant Street area is the seat of Pittsburgh's and Allegheny County's government and is also a prestigious corporate address with many of the city's tallest skyscrapers.
• The Firstside neighborhood along the Boulevard of the Allies and Fort Pitt Boulevard adjacent to the Monongahela River is an educational and residential district. It is home to Point Park University and the Art Institute of Pittsburgh both of which have high-rise student housing in the neighborhood. Numerous other residential projects are also under construction in this neighborhood.

Downtown Pittsburgh retains substantial economic influence, ranking at 25th in the nation for jobs within the urban core and 6th in job density.

University of Pittsburgh economist Christopher Briem notes that the level of employment in the city has remained largely constant for the past 50 years: "[the] time series of jobs located in the City proper are about as stable as any economic metric in the region, or in any other Northeastern US urban core, over many decades. In 1958, [there were] 294,000 jobs located in the city proper...Those numbers are virtually identical today which tells me there is a certain limit to how many jobs can efficiently be located in what are some relatively (very) constrained areas." These numbers reflect employment in the city as a whole, not just the central business district; but the central business district has the highest density of employment of any Pittsburgh neighborhood.

Pittsburgh has long been a headquarters city, with numerous national and global corporations calling the Golden Triangle home.
