Dallas City Hall is the seat of Dallas municipal government, located at 1500 Marilla in the Government District of downtown Dallas, Texas (USA). The current building, the city's fifth city hall, was completed in 1978 and replaced the Dallas Municipal Building.
The City of Dallas’ idea for a centralized municipal center began when city planning consultants Harland Bartholomew & Associates presented their ideas in 1944. The idea was to relocate from the current Dallas Municipal Building to a grand Beaux-Arts complex of city and federal offices, a convention center and cultural facilities. Two sites downtown were possible contenders: one north centered around Federal Street and Akard, and one south centered around Young Street.
Plans proceeded until cost estimates shocked city leaders and the plan was shelved, although land at the southern site was acquired by the city for future use.
The 1963 assassination of President John F. Kennedy turned the world against the city, as Dallas became known as the “City of Hate.” Dallas Mayor Erik Jonsson made it a priority to reinvent the city’s image, and the “Goals for Dallas” program was enacted to accomplish this. One of goals, Design of the City, was summarized by the statement, "We demand a city of beauty and functional fitness that embraces the quality of life for all its people."  This was the start of the movement to create a new modern City Hall and municipal center.
Planning for the Dallas Municipal Center commenced in 1964 when the Dallas City Council appointed a Citizen's City Hall Site Committee to select an appropriate location for new municipal administration offices. The mayor was closely involved with the project, and a committee of prominent citizens settled on I.M. Pei to design the new facility.
Construction began on June 26, 1972 under the direction of contractor Robert E. McKee and Pei. The project was completed in three phases. The City accepted the garage parking areas in November 1974; the Park Plaza in May 1976; and the building in December 1977. The cost of design and construction of the building, the Park Plaza and the garage was over $70 million. Controversies arose over cost overruns (the original estimated cost was $42.2 million) and aesthetic issues (was the building too avant-garde?), though most problems were addressed and work moved on to completion.
The first Dallas City Council meeting was held in the building's City Council Chamber on February 1, 1978, and the entire facility was formally opened and dedicated on March 12, 1978.
"When you do a city hall, it has to convey an image of the people, and this had to represent the people of Dallas... The people I met – rich and poor, powerful and not so powerful – were all very proud of their city. They felt that Dallas was the greatest city there was, and I could not disappoint them." – I.M. Pei
I.M. Pei’s modernist inverted pyramid design is a result from space requirements of city government. Public areas and citizen services required much less space than offices that ran the government; cantilevered building levels allowed for the upper levels to house the offices. The building slopes at a 34° angle, with each of the 7 above-grade floors being 9½ feet wider than the one below. This inclined façade interacts with the buildings it faces downtown and provides protection from the weather and Texas sun.
The foundation and basement levels are considerably wider than the apparent footprint of the structure, extending out beneath the inclined facade. The cantilevered roof is 200 feet (61 meters) wide, the ground floor is 126 feet (38.4 meters) wide, and the basement 230 feet (70.1 meters) wide. When Mayor Jonsson reacted to the apparent top-heaviness of the building's shape, 3 cylindrical pillars that appear the hold up the structure were created. These contain stairwells that had originally been concealed within the design. These pillars only provide visual support and do not bear the load of the building.
Pei also persuaded the city to acquire an additional 6 acres in front of the building as a plaza and buffer zone for his grand public structure. A 1,325 car parking garage was built beneath the plaza, and the extra income helped supplement the funding of the building.
A buff-colored concrete was chosen for the main building material; its color resembled local earth tones. Since concrete was both the primary structural and finish material, close attention was paid to every aspect of its mix and placement.
The design of Dallas City Hall inspired the J. Erik Jonsson Central Library building located across the street – whereas the upper floors of City Hall are oriented toward Marilla Street, the upper floors of the Central Library are oriented away from Marilla (and, in a form of symmetry, away from City Hall).\
The building features in the Robocop movies of the 1980s, as the Headquarters of the OCP company. In the movies, the building looks different from the actual building, in that, it is made up to be a multi-story building, using special effects. 
- City Hall contained 1,400 workstations when it opened in 1978. It had few floor-to-ceiling walls, using instead five-, six-, and seven-foot-high partitions to create separate offices. The absence of walls allowed employees and visitors to have window views from all areas.
- The second floor of Dallas City Hall is referred to as the Great Court because of its 250-foot (76 m) length and the uninterrupted height to the vaulted ceiling approximately 100 feet (30 m) above.
- The Park Plaza is two blocks long and one block wide and is bounded by Young, Ervay, Marilla and Akard streets. The Plaza includes a 180-foot (55 m)-diameter reflecting pool, a variable-height fountain, park benches and three distinctive 84-foot (26 m)-high flagpoles. The Plaza is landscaped with trees native to Texas: live oaks and red oaks. The reflective pool contains large floating sculptures designed by artist Marta Pan.
- A 16-foot (4.9 m)-high by 24-foot (7.3 m)-wide, three-piece sculpture titled "The Dallas Piece" was designed by Henry Moore for the plaza and resembles vertebrae.
- A state-of-the-art Conference Center that includes a 156-seat auditorium and three conference rooms was recently added to Dallas City Hall.
- A tunnel and station for future rail transit was constructed in the third level basement beneath the parking garage and Marilla Street. This tunnel has remained unused but has been considered for DART’s second light rail route through downtown Dallas.
City Hall Plaza is regularly used for marches and protests
