PureBasic是由Fantaisie Software所开发的商用BASIC进程语言及集成开发环境（IDE）。特点是语法简单直接，不依赖运行时库，因此能编译出相当小巧的进程，包含命令行或GUI运行档、DLL等。而且不使用各系统的API，所以有高度的跨平台特性，支持Windows 32/64比特、Linux 32/64比特、Mac OS X、Amiga。

PureBasic is a commercially distributed procedural computer programming language and integrated development environment based on BASIC and developed by Fantaisie Software for Windows 32/64-bit, Linux 32/64-bit, and Mac OS X. An Amiga version is available, although it has been discontinued and some parts of it are released as open source. The first public release of PureBasic for Windows was on December 17, 2000. It has been continually updated since.
