Microsoft Office Access（前名Microsoft Access）是由微软发布的关系数据库管理系统。它结合了Microsoft Jet Database Engine和图形用户界面两项特点，是Microsoft Office的系统程序之一。

Access能够访问Access/Jet、Microsoft SQL Server、Oracle，或者任何ODBC兼容数据库内的数据。熟练的软件设计师和数据分析师利用它来开发应用软件，而一些不熟练的程序员和非程序员的高端用户则能使用它来开发简单的应用软件。虽然它支持部分面向对象技术，但是未能成为一种完整的面向对象开发工具。

Microsoft Access is a DBMS (also known as Database Management System) from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately.
