NTFS符号链接（Symbolic Link），又称符号链接，是NTFS文档系统中指向文档系统中的另一个对象的一类对象。被指向的对象叫做“目标”。它们可以像普通文档一样操作，但所有对符号链接的操作都实际作用于目标对象。符号链接对用户而言是透明的，符号链接看上去和普通的文档和文档夹没有区别，操作方法也一模一样。NTFS符号链接的设计目的是为了和POSIX标准的操作系统兼容、并用来增进与旧版操作系统的兼容性，它首次出现于Windows Vista。

Windows 2000开始就有的NTFS连接点，只能用于目录，且只能用于本地文档系统。而符号链接既可以指向本地文档，也可以指向远程SMB网络路径。NTFS连接点只支持本地驱动器的绝对路径，但NTFS符号链接允许使用相对路径。还有，NTFS符号链接允许跨文档系统使用，但是对于跨主机的符号链接，还需要远程机器也支持这一功能才行。

An NTFS symbolic link (symlink) is a filesystem object in the NTFS filesystem that points to another filesystem object. The object being pointed to is called the target. Symbolic links should be transparent to users; the links appear as normal files or directories, and can be acted upon by the user or application in exactly the same manner. Symbolic links to directories or volumes, called junction points and mount points, were introduced with NTFS 3.0 that shipped with Windows 2000. From NTFS 3.1 onwards, symbolic links can be created for any kind of file system object. NTFS 3.1 was introduced together with Windows XP, but the functionality was not made available (through ntfs.sys) to user mode applications. Third-party filter drivers – such as Masatoshi Kimura's opensource senable driver – could however be installed to make the feature available in user mode as well. The ntfs.sys released with Windows Vista made the functionality available to user mode applications by default.
