Fieldata was a pioneering computer project run by the US Army Signal Corps in the late 1950s that intended to create a single standard for collecting and distributing battlefield information. In this respect it could be thought of as a generalization of the US Air Force's SAGE system that was being created at about the same time.

Unlike SAGE, Fieldata was intended to be much larger in scope, allowing information to be gathered from any number of sources and forms. Much of the Fieldata system was the specifications for the format the data would take, leading to a character set that would be a huge influence on ASCII a few years later. Fieldata also specified the message formats and even the electrical standards for connecting Fieldata-standard machines together.

Another part of the Fieldata project was the design and construction of computers at several different scales, from data-input terminals at one end, to theatre-wide data processing centers at the other. Several Fieldata-standard computers were built during the lifetime of the project, including the transportable MOBIDIC from Sylvania, and the BASICPAC and LOGICPAC from Philco. Another system, ARTOC, was intended to provide graphical output (in the form of photographic slides), but was never completed.

The Fieldata project ran from 1956 until it was stopped during a reorganization in 1962.
