José Manuel Romero Moreno (Madrid, 11 June 1940) is a Spanish lawyer and university professor.
In 1981 he received his doctorate for his thesis entitled "Fundamental rights and procedural protections in the nineteenth century in Spanish".
In 1993 after his mother's death, he inherited the titles of Count of Fontao and Marquis of San Saturnino, continuing the family ties with the province of Lugo.
That year King Juan Carlos appointed Romero as his Household's external legal counsel.
In December 2011 the press discovered that, as private legal adviser to the King, Romero Moreno had been trying to force Inaki Urdangarin to cease his commercial activities linked to what later was called the Nóos case.
