Maurice Rajsfus (9 April 1928 – 13 June 2020) was a French writer, journalist, historian and anti-establishment militant.

He was the author of numerous books addressing themes such as the Jewish genocide in France, the police, and attacks on civil liberties.

In what came to be known as the Vel' d'Hiv Roundup more than 13,000 Jews were rounded up in and around Paris by French police and officials, to be held in appalling conditions in a velodrome before being shipped to the Auschwitz concentration camp.

[7] Since 1988 Rajsfus has repeatedly recalled that brief discussion in interviews and published work, referring to the "Vichy police whose past today remains very much with us, without remorse and without memory" ("...police de Vichy au passé trop présent, sans remords et sans mémoire...").

He was active in the Fourth International before 1950, and then in the "Socialism or Barbarism" libertarian socialist group with Claude Lefort and Cornelius Castoriadis, mobilising the Youth Hostel Movement in opposition to the Algerian War after 1955.

[5] One year after the killing, on 6 April 1993, of Makomé M'Bowolé[8] by a "bullet grazing his head"[1] while he was handcuffed and under interrogation at the Grandes Carrières police station,[9] Maurice Rajsfus co-founded the "Observatory of Public Liberties" ("l'Observatoire des libertés publiques"), which produces a monthly bulletin entitled "Que fait la police?"

[12] He also denounced the use of the antisemitism accusation which he described as "a weapon raised against anyone who opposes Zionism, an active ideology that should not be allowed to face the least criticism".
