Niurka Marcos Calle (born November 25, circa 1977) is a Cuban-Mexican singer, dancer and actress who was born in Havana. She is better known plainly as Niurka Marcos.

Marcos already had a son when she moved to Mexico, leaving him behind to look for a better future. She was a little-known actress in Cuba.

In Mexico, she started having some mild success on Televisa Spanish Soap Operas, until she met producer Juan Osorio. Marcos and Osorio began dating in 1998.

Marcos then became a star on many of Osorio's productions, they moved together and had children. Niurka Marcos and another actress started receiving threatening calls at their homes in 2003. So far, police have not been able to identify the perpetrator of these calls.

Marcos and Osorio were planning to get married in February of 2004. Early in January, however, she shocked the Mexican media, and the Latin American media in the United States, by revealing that she had been having an affair with her Lazos de Amor co-star Boby Larios, and that she was leaving Osorio for Larios. The news caused a wide-spread scandal, and Marcos has not spared Osorio from public insult, blaming the break up on, among other things, lack of sexual relations between the two.

Niurka Marcos has also released a CD, named Niurka.
