Two Undercover Angels (Spanish: El caso de las dos bellezas, lit. 'The Case of the Two Beauties') is a 1969 film directed by Jesús Franco.

The film is a Spanish and West German co-production, shot throughout Spain and Munich in 1967. It was the second of Franco's three-film deal with Aquila Films Enterprises, following Succubus (1968). It was also the second appearance of "The Red Lips", a duo of female secret agents who could continue to show in various films made by Franco into the 1990s.

The film received generally positive reviews in Spanish newspapers La Vanguardia and ABC Andalucia who both found the film entertaining, while the latter was upset that Franco was pursuing predominantly commercial cinema, instead of work of more artistic merit.
