La Mujer Muerta (English translation: “The Dead Woman”) is a subrange of the Sierra de Guadarrama, Sistema Central, located in Segovia Province, Spain.

There are many legends that try to explain the name, La Mujer Muerta, with the mountains La Pinareja, Peña el Oso, and Pico de Pasapán that form, when viewed from the city, the body of a woman that is dead or sleeping.

One story is that the woman's husband went off to war and failed to keep his promise that he would return and marry her.

According to this, the peak of La Pinareja corresponds to the face of the woman laying on her back.

On 4 December 1958, an Aviaco SNCASE SE.161 Languedoc flying from Vigo Airport to Barajas Airport, Madrid lost height in bad weather and struck La Rodilla de la Mujer Muerta.
