Xavier Rubert de Ventós (1 September 1939 – 28 January 2023) was a Spanish philosopher, writer and politician.

[2] Rubert de Ventós was arrested three times for his activities as a member of the Workers' Front of Catalonia.

In 1975 threats from Falangists forced him into exile in Paris, during which time he was expelled from the University of Barcelona for abandoning his position.

Rubert de Ventós was also a member of the Commission for Dignity (comisión para reparar la dignidad y restituir la memoria de las víctimas del franquismo), an entity that calls for the return to their rightful owners of documents that were confiscated at the end of the Civil War and subsequently housed in the General Civil War Archive in Salamanca.

In November 2012, he signed a public manifesto in which he supported the centre-right Convergence and Union (Convergència i Unió) in the elections to the Parliament of Catalonia.
