Lisp机器（英语：Lisp machines）是被设计来高效运行以Lisp语言为主要软件开发语言的通用型计算机（通常通过硬件支持）。在某种意识上，它们是第一个商业的单用户工作站。尽管在数量上表现不如意（在1988年大概只有7000套），Lisp机器在商业上开创了许多现行的技术，包括高效的内存垃圾收集，激光打印，窗口化系统，计算机鼠标，高分辨率的位图，计算机图像解析和网络革新（像CHAOSN）。在上世纪八十年代，几家公司正建造和销售Lisp机器：Symbolics(3600,3640,XL1200,Maclvory和其他模型），Lisp Machines Incorpaorated（LMI Lambda），Texas Instruments（Explorer和MicroExplorer）和Xerox（InterLisp-D workstations）。这些操作系统都是用Lisp Machine Lisp,InterLisp(Xerox)和稍后出现的Common Lisp写的。

Lisp machines are general-purpose computers designed to efficiently run Lisp as their main software language, usually through hardware support. They are an example of a high-level language computer architecture, and in a sense, they were the first commercial single-user workstations. Despite being modest in number (perhaps 7,000 units total as of 1988), Lisp machines commercially pioneered many now-commonplace technologies – including effective garbage collection, laser printing, windowing systems, computer mice, high-resolution bit-mapped graphics, computer graphic rendering, and networking innovations like Chaosnet. Several companies built and sold Lisp Machines in the 1980s: Symbolics (3600, 3640, XL1200, MacIvory, and other models), Lisp Machines Incorporated (LMI Lambda), Texas Instruments (Explorer and MicroExplorer), and Xerox (Interlisp-D workstations). The operating systems were written in Lisp Machine Lisp, InterLisp (Xerox), and later partly in Common Lisp.
