实验室信息管理系统（Laboratory Information Management System,缩写LIMS）是一套用来管理实验室的样品、实验室人员、仪器、标准品和其他实验室活动（如采购、实验流程自动控制等）。实验室信息管理系统和实验室信息系统有着相同的功能，最基本的区别在于实验室信息管理系统的主要目的在于制药和石化生产过程的环境、研究和商业分析，而实验室信息系统的是针对临床市场（如医院或其他临床实验室）。

A laboratory information management system (LIMS), sometimes referred to as a laboratory information system (LIS) or laboratory management system (LMS), is a software-based laboratory and information management system with features that support a modern laboratory's operations. Key features include — but are not limited to — workflow and data tracking support, flexible architecture, and data exchange interfaces, which fully "support its use in regulated environments." The features and uses of a LIMS have evolved over the years from simple sample tracking to an enterprise resource planning tool that manages multiple aspects of laboratory informatics.
