Johannes Adrianus Menne Warren (20 October 1921, in Borssele – 19 December 2001, in Goes[1]) was a Dutch writer.

In 1951, he began to write reviews and literary criticism for the Provinciale Zeeuwse Courant, one of the foremost newspapers in Zeeland.

Soon after their marriage his wife was offered a position in Paris, where Warren's repressed homosexual feelings found an outlet in many contacts with North African boys.

In 1969 Warren met Gerrit Komrij and the two poets began a long and mutually inspiring friendship.

Warren openly describes his own life and experiences, and offers his opinions on everyone, including his friends.

Warren died at age 80 of liver problems; even his final year is described in his diary (which he kept until three days before his death) and in that of Molegraaf (published in 2002).
