A '''Perl module''' is a discediscrete component of software for the [[Perl]] programming language. Technically, it is a particular set of conventions for using Perl's [[#Perl packages and namespaces|package]] mechanism that has become universally adopted.{{discuss|Packages and modules}}

A module defines its source code to be in a ''package'' (much like a [[Java package]]), the Perl mechanism for defining [[namespaces]], e.g. ''CGI'' or ''Net::FTP'' or ''XML::Parser''; the file structure mirrors the namespace structure (e.g. the [[source code]] for ''Net::FTP'' is in ''Net/FTP.pm''). Furthermore, a module is the Perl equivalent of the [[class (computer science)|class]] when [[object-oriented programming]] is employed.{{discuss|Packages and modules}}
