London Psychogeographical Association (LPA) is a fictional "association" created by absurdists.

The term was originally used by the British artist Ralph Rumney. A fictional and non-internally consistent history of the group accreted over time, including the dissolution of the "group" into the Situationist International in Italy in 1957 and the expulsion of Rumney from the SI on the pretext of a tardy "psychogeographical" report.

Another fabrication, called the East London Section was "founded" around 1994, by Richard Essex. This group, it is said, took a "psychogeographical" trip to Roisa's Cave in Royston and issued a LPA Newsletter which continued till issue 21.

Other claimed historical tidbits, which cannot be verified:

• LPA collaborated with a Neoist Alliance
• the foundation of a New Lettrist International
• the attribution of the LPA Newsletter to Stewart Home
• the decision of the LPA to adopt a modern Khemetic calendar
• the disbanding of the LPA in 1998
• the connection with the evoL PsychogeogrAphix
