Juan Manuel Álvarez (born February 26, 1979), a laborer from Compton, California, is a Californian convicted of causing the January 26, 2005, Glendale train crash, a collision between a passenger train, another passenger train, a freight train, and a car in Glendale, California (a suburb of Los Angeles).

He parked his gasoline-soaked sport-utility vehicle on the tracks and waited for a southbound Metrolink commuter train. At the approach of the train, allegedly unable to move his vehicle from the tracks, he exited, apparently abandoning a suicide attempt, and observed the train colliding with his SUV (causing the train to derail) from a safe distance.

The derailed train then hit a Union Pacific Railroad freight train parked on a siding, as well as a northbound Metrolink train on the third track. The collision left 11 people dead and nearly 200 injured.

Alvarez was allegedly suicidal long before the incident occurred. According to some reports, he had attempted suicide previously. In addition, he was a known methamphetamine addict, prone to delusional behavior. At the time of the train crash, Alvarez, the father of two young children, was experiencing marital difficulties.

Alvarez was sentenced to 11 life terms for the murders.
