The Constitutional Court of Hungary is a special court of Hungary, making judicial review of the acts of the Parliament of Hungary. The official seat of the Constitutional Court is Budapest. Until 2012 the seat was Esztergom.

Esztergom is a city with county rights in northern Hungary, 46 kilometres northwest of the capital Budapest. It lies in Komárom-Esztergom County, on the right bank of the river Danube, which forms the border with Slovakia there. Esztergom was the capital of Hungary from the 10th until the mid-13th century when King Béla IV of Hungary moved the royal seat to Buda.
