Casa Real (Royal House) is one of the oldest public buildings and served as the provincial seat of government of Lingayen, Pangasinan, in the Philippines during the Spanish colonial period.

In the 1840s, the 1,480-square-meter, two-story Casa Real made of stone masonry and bricks, which stands at the municipal plaza, was constructed.

When Judge William Howard Taft and his commissioners went to Lingayen, Pangasinan, they were given a grand reception at Casa Real on February 16, 1901.

Five million pesos was allocated for its initial phase of renovation, to turn the currently inhabitable building into a museum that would house old books, documents, artifacts, archaeological relics and other memoirs of historical and cultural values of Pangasinan during the Spanish and American periods.

Pangasinan Representative Leopoldo Bataoil proposed the allocation of thirty million pesos from 2015's national budget to add to its initial funding.
