The Guest Court (Polish: Gościnny Dwór) was a market hall in Warsaw, Poland, operating between 1841 and 1939.

It was located in the neighbourhood of North Downtown, at the intersection of Rynkowa and Skórzana Streets, and the Iron Gate Square.

The Guest Court was commitioned by the Administrative Council, and designed by Jan Jakub Gay and Alfons Kropiwnicki, and constructed in October 1841 next to the Iron Gate Square, to help organize trade in the town of Wielopole.

It was named after Russian-language term gostiny dvor (Cyrylic: гостиный двор; original spelling: Гостинный дворъ), referring to numerous retail buildings in the Russian Empire.

It had a shape of a isosceles triangle with curved corners, and circumference of around 280 m. It was built from bricks, with zinc roof, and arcades made with cast iron.
