Joaquín Ruiz-Giménez Cortés (Hoyo de Manzanares, Madrid, August 2, 1913 - Madrid, August 27, 2009) was a Spanish politician and jurist.
He was minister of Education under Franco (1951-1955) but he drifted apart from the Francoist State since 1956 and, adopting a Christian Democrat position, steadily started to promote a quiet transition to democracy, especially through Cuadernos para el Diálogo magazine.
He was considered one of the most relevant figures of the moderate inner opposition to Francoism.
Failing to play a relevant role during the 1977 democratic elections, he was later elected as the first Spanish Ombudsman.
