Vilma Lucila Espín Guillois (7 April 1930 – 18 June 2007) was a Cuban revolutionary, feminist, and chemical engineer.

She helped supply and organize the 26th of July Movement as an underground spy, and took an active role in many branches of the Cuban government from the conclusion of the revolution to her death.

[5] Espín attended Academia Pérez-Peña for primary school and studied ballet and singing at the Asociación Pro-Arte Cubano during the 1940s.

[7] After graduating, her father encouraged her to attend MIT in Cambridge, Massachusetts to complete her post-graduate studies in the hopes that visiting America would dissuade her from becoming involved in socialist activity.

[8] When she finally acquiesced, her brief academic career at MIT left her with even more animosity toward the United States, as she officially joined the 26th of July Movement on her way back to Cuba through Mexico.

Espín met the Castro brothers who had relocated to Mexico after their failed armed attack on the Moncada Barracks in July 1953 and release from prison in 1955.

She then went on to assist the revolutionaries in the Sierra Maestra mountains after the 26th of July Movement's return to Cuba on the Granma yacht in November 1956.

[9][10] Pepín Bosch, an executive of the Bacardi Corporation, arranged a meeting between CIA Inspector General Lyman Kirkpatrick and representatives of the 26th of July Movement in 1957.

[9] Vilma Espín was an outspoken supporter of gender equality in Cuba,[9] but distinctly separated herself and the goals of the Federation of Cuban Women from traditional feminism, insisting advocacy for 'feminine' not 'feminist'.

The organization's primary goals were educating women, giving them the necessary skills to seek gainful employment, and above all encouraging them to participate in politics and support the revolutionary government.
