Joaquín Satrústegui (born Satrústegui Joaquín Fernández, San Sebastián, 17 October 1909 - 11 March 1992 ) was a Spanish lawyer and political monarchist.
He fought on the Nationalist side during the Spanish Civil War, and evolved from the ultra-conservatism of his youth into liberal positions, always within monarchist sectors.
He was one of those attending the conference of the European Movement held in Munich in 1962 (referred to as the " Munich conspiracy" in Francoist Spain).
After the Spanish transition to democracy he was successively elected senator and congressman.
