The Parliament House (Maltese: Dar il-Parlament) is the meeting place of the Parliament of Malta located in Valletta, Malta. The building was constructed between 2011 and 2015 to designs by Renzo Piano as part of the City Gate Project, which also included building a new City Gate and converting the ruins of the Royal Opera House into an open-air theatre. Construction of the Parliament House generated considerable controversy, mainly due to the modern design of the building and the cost of construction, which amounted to around €90 million.

From 1921 to 1976, the meeting place of the Parliament of Malta had been the Tapestry Chamber of the Grandmaster's Palace, also in Valletta. In 1976, the former armoury of the same palace was converted into a new parliament, and meetings were held there until the opening of the purpose-built Parliament House on 4 May 2015.

The Parliament House is located in Republic Street near City Gate, the entrance to Valletta. The building is located adjacent to Saint James Cavalier and the ruins of the Royal Opera House, and opposite the City Gate Shopping Arcade and Palazzo Ferreria.^{[citation needed]}

The site presently occupied by the Parliament House originally contained houses, and later the Valletta Station of the Malta Railway. The area was bombarded during World War II, and the station and surrounding buildings were demolished in the 1960s as part of a project to redevelop the entrance to Valletta. The area was converted into an open space known as Freedom Square (Maltese: Misraħ il-Ħelsien), which was surrounded by a shopping arcade. The square was originally rather plain, and was commonly used as a car park.

Though most of the square has been built-up, part of it is still officially the Freedom Square, and is now in a rectangular form. The square now covers from the corner of Palazzo Ferreria to the first column across of the subjected parliament, and to the Spanish steps next to the City Gate.

The building of the Parliament House was a part of the City Gate Project, which was meant to redevelop the entrance of Valletta. The project consisted of the demolition of the fourth City Gate and the Freedom Square Arcade and the construction of the fifth City Gate and the Parliament House. In addition, the ruins of the Royal Opera House were converted into an open-air theatre known as Pjazza Teatru Rjal. The City Gate project was designed by the Italian architect Renzo Piano, and the plans were revealed on 27 June 2009. The Grand Harbour Regeneration Corporation paid Piano €6.6 million for his work on the project.

The demolition of the arcades of Freedom Square began in October 2010. Excavation works for the foundations of the Parliament House began soon after demolition was complete. In early 2011, the original plan was modified with the relocation of a staircase, the extension of one of the blocks, and changes in the design of the louvers on the facade. Construction started later that year, and the steel frame of the structure was complete by early 2012. At this point, it began to be covered in limestone which had been quarried in Gozo, and cut into specific shapes in Italy, before being sent back to Malta. Between 120 and 150 workers were on the construction site every day, and it cost more than €90 million to build.

The completion date of the project was originally given as November 2012 or early 2013. The estimated completion date was extended to September 2013, and later to September 2014. Contractors failed to meet deadlines, and the building was still not complete by the end of 2014. It was eventually completed in 2015.
