Perlembagaan Sepanyol mengisytiharkannya sebagai raja berperlembagaan. Dari tahun 1833 hingga 1939 Sepanyol hampir secara berterusan mempunyai sistem parlimen dengan perlembagaan bertulis. Kecuali semasa Republik Pertama (1873–74), Republik Kedua (1931–36), dan Perang Saudara Sepanyol (1936–39), Sepanyol selalu mempunyai monarki. Raja adalah ketua negara, tetapi peranan mahkota ditakrifkan sebagai benar-benar berkecuali dan apolitik.
