CPAN（Comprehensive Perl Archive Network）中译为“Perl综合典藏网”，“Perl综合档案网”或者“Perl进程库”。它包含了极多用Perl写成的软件和其文档。

CPAN亦是一支Perl程序的名字，其作用是让用户容易从CPAN下载、安装、更新及管理其他在CPAN上的Perl程序。

CPAN的成功引来很多其他编程语言社区的模仿。CTAN和CSAN都参考了CPAN的命名方式。另外PEAR（PHP Extension and Application Repository）也是类似CPAN的PHP程序网站。

CPAN, the Comprehensive Perl Archive Network, is a software repository of over 150,929 modules of software in 33,069 distributions, written by 12,528 authors, written in the Perl programming language, as well as documentation for them. The modules can be downloaded from metacpan.org and also from mirrored sites worldwide. CPAN can denote either the archive network itself, or the Perl program that acts as an interface to the network and as an automated software installer (somewhat like a package manager). Most software on CPAN is free and open source software. CPAN was conceived in 1993 and active online since October 1995.
