Miquel Roca Junyent (Bordeaux, France, 20 April 1940) is a Spanish lawyer and politician from Democratic Convergence of Catalonia.

He was elected to the first democratic parliament after the Francoist dictatorship for the district of Barcelona, where he held his seat from 1977 to 1995 in representation of Convergence and Union.

During this period, he failed in his attempt to create a centrist party to act as a counterweight between the conservative People's Alliance and the social-democratic PSOE, a plan known as Operation Roca.

Roca was hired by the Spanish royal family to defend Cristina de Borbón in the judicial procedures against her in the Noos case.

In May 2016, judge José Castro denounced pressures by Roca and his law firm to have a meeting in order to acquit Borbón from all charges pressed against her.
