The Palace of the Parliament (Romanian: Palatul Parlamentului), also known as the House of the Republic (Casa Republicii) or People's House/People's Palace (Casa Poporului), is the seat of the Parliament of Romania, located atop Dealul Spirii in Bucharest, the national capital. The Palace reaches a height of 84 m (276 ft), has a floor area of 365,000 m² (3,930,000 sq ft and a volume of 2,550,000 m³ (90,000,000 cu ft). The Palace of the Parliament is the heaviest building in the world, weighing about 4,098,500 tonnes (9.04 billion pounds), and is the third largest administrative building in the world.

The building was designed and supervised by chief architect Anca Petrescu, with a team of approximately 700 architects, and constructed over a period of 13 years (1984–1997) in modernist Neoclassical architectural forms and styles, with socialist realism in mind. The Palace was ordered by Nicolae Ceaușescu (1918–1989), the president of Communist Romania and the second of two long-ruling heads of state in the country since World War II,during a period in which the personality cult of political worship and adoration increased considerably for him and his family

Known for its ornate interior composed of 23 sections, the palace houses the two chambers of the Parliament of Romania: the Senate (Senat) and the Chamber of Deputies (Camera Deputaților), along with three museums and an international conference center. The museums in the Palace are the National Museum of Contemporary Art, the Museum of Communist Totalitarianism (established in 2015) and the Museum of the Palace. Though originally named the House of the Republic when under construction, the palace became widely known as The People's House after the Romanian Revolution of December 1989. Due to its impressive characteristics, events organized by state institutions and international bodies such as conferences and symposia take place there, but despite this about 70% of the building remains empty.

As of 2020, the Palace of the Parliament is valued at €4 billion, making it the most expensive administrative building in the world. The cost of heating, electricity, and lighting alone exceeds $6 million per year.

The old Palace of the Chamber of Deputies is now the Palace of the Patriarchate.

The trial and execution of Nicolae and Elena Ceaușescu were held on 25 December 1989 in Târgoviște, Romania. The trial was conducted by an Extraordinary Military Tribunal, a drumhead court-martial created at the request of a newly formed group called the National Salvation Front. Its outcome was predetermined, and it resulted in guilty verdicts and death sentences for former Romanian President and General Secretary of the Romanian Communist Party Nicolae Ceaușescu, and his wife, Elena Ceaușescu. The main charge was genocide. Romanian state television announced that Nicolae Ceaușescu had been responsible for the deaths of 60,000 people; the announcement did not make clear whether this was the number killed during the Romanian Revolution in Timișoara or throughout the 24 years of Ceaușescu's rule.

Nevertheless, the charges did not affect the trial. General Victor Stănculescu had brought with him a specially selected team of paratroopers from a crack regiment, handpicked earlier in the morning to act as a firing squad. Before the legal proceedings began, Stănculescu had already selected the spot where the execution would take place: along one side of the wall in the barracks' square.

Nicolae Ceaușescu refused to recognize the tribunal, arguing its lack of constitutional basis and claiming that the revolutionary authorities were part of a Soviet plot. His refusal to recognize the tribunal did not prevent the firing squad from carrying out the sentence immediately, on the same day as the trial.
