The Prussian House of Representatives (German: Preußisches Abgeordnetenhaus) was, until 1918, the second chamber of the Prussian Landtag, the other chamber being the Prussian House of Lords. It was established by the Prussian constitution of 5 December 1848, with members elected according to the three-class franchise. The name "House of Representatives" (Abgeordnetenhaus) was introduced in 1855.
