The Parliament Building of Quebec is an eight-floor structure and is home to the National Assembly of Quebec, in Quebec City, Quebec, Canada. The Parliament Building was designed by architect Eugène-Étienne Taché in a Second Empire style and built between 1877 and 1886, in the heart of Quebec's Parliament Hill. The National Assembly first met there on March 27, 1884, even though the building was only fully completed two years later, on April 8, 1886. From the 1910s to the 1930s, the government built several adjacent buildings to expand its office spaces, creating a parliamentary complex, of which the Parliament Building is the main edifice. This structure is a successor of several earlier buildings, the earliest of which was built in 1620 and among which there were two other parliament houses that served as legislatures.

The National Assembly of Quebec is the legislative body of the province of Quebec in Canada. Legislators are called MNAs. The lieutenant governor of Quebec and the National Assembly compose the Legislature of Quebec, which operates in a fashion similar to those of other Westminster-style parliamentary systems. The assembly has 125 members elected first past the post from single-member districts.
