Santa Margarita is a Gated community (known as an urbanization in Spanish) in the northern suburb of La Línea de la Concepción in the Province of Cádiz, Andalucia, Spain.

[1] Santa Margarita is a luxury residential development a stone's throw away from Gibraltar on the outskirts of La Linea de La Concepcion.

In July 2016 a wildfire forced the evacuation of some of the properties in Santa Margarita.

In January 2017 La Linea Council had meetings with Novarent, to investigate building another urbanization on 60 hectares of land called Cortijo de San Antonio which is bordered on the south by the Venta Melchor urbanization in Santa Margarita, with the idea of calling it 'English City' to attract more British people to the area and provide an economic impulse which is much needed by the local community.

The town hall has ambitious plans to generate a substantial number of jobs and ensure that the project delivers on this front.
