Grecia Dolores Colmenares Mieussens (Latin American Spanish: [ˈɡɾesja kolmeˈnaɾes]; born 7 December 1962) is a Venezuelan actress.

Grecia Colmenares became a sensation as a young actress in her native Venezuela during the 1970s, becoming a favorite of the general public in that country.

Although her jobs in Venezuela gave her considerable international fame, it was after she moved to Argentina that Colmenares became paparazzi fodder.

In 1999, Colmenares acted in a telenovela that Del Boca had previously participated in: Chiquititas, which had by then become a major international hit.

In Venezuela, Colmenares and Victor Camara formed a popular on-camera couple, starring together in a number of soap operas.
