The ALe 582 is an Italian electric multiple unit train designed for commuter and medium-distance services, developed in the mid-1980s to replace pre-war and immediately post-war EMUs and locomotive-hauled trains on various lines in Sicily and Southern Italy, although they later diffused on the whole FS network.

The ALe 582 project was developed in the mid-eighties in order to replace old rolling stock used for commuter traffic and medium-distance (regional and local services) on secondary lines of Sicily and southern Italy.

It is a strict derivative of the ALe 724 Class, which was introduced in 1983 for commuter services around Naples, Milan and Turin.

The most noticeable (and one of the very few) difference from the ALe 724s is the redesigned FRP-made cab front, designed to cope with new crash-worthiness regulations.

Starting from 2009, ex-Trenitalia units handed over to Trenord received the latter's dark green and white livery.

The electronics and traction control equipment is concentrated in a dedicated compartment, called "A.T." (Alta-Tensione, "High-Voltage" comparto) located between the driving cab and the first passenger door on ALe 582.
