FileMan is a set of utilities written by George Timson in the late 1970s and early 1980s, using MUMPS, which provide a meta-data function for MUMPS applications. The FileMan utilities allow the definition of data structures, menus and security, reports, and forms, allowing someone to set up applications without tremendous experience in the MUMPS programming language.

Its first use was in the development of medical applications for the Veterans Administration, now called the Department of Veterans Affairs, a branch of the United States Government. Since it was a work created by the government, a copyright cannot be placed on the source code, making the source code in the public domain. Because of this, it has been used for rapid development of applications across a number of organizations, including commercial products.

FileMan may be used standalone, or may be used with the VA Kernel, which provides an operating system neutral environment for applications.
